Basic Mathematics 1 LO 4. % Formula
Percentage Formula The formula to use in percent calculations is: Portion = Rate *Base Formula …using the‘Triangle’ will help us remember the above formula! Question is asking for… P= “…is ” or “…are ” This indicates the Portionthat has to be found! R= “%” indicates the Rate P B = “…of ” indicates the Base which is 100% or 1 R B
Using this tool! P P = R*B P/R=B R B Percentage Formula The formula to use in percent calculations is: Portion = Rate *Base Formula Where variables are BESIDE EACH OTHER this means to MULTIPLY! Where a variable is ABOVE ANOTHER this means to DIVIDE!
The formula to use in percent calculations is: Portion = Rate *Base Formula Using this tool! P R B Percentage Formula thenR*B If you want to find P thenP/B If you want to find R If you want to find B thenP/R
Q Portion = Rate *Base Formula P R B Percentage Formula Solving for Portion Salesof McDonalds drive-thru customers are60%of total sales. TotalMcDonaldsalesare$1,600,000. Whatarethe drive-thru sales? What do you have to find? 60% * P = $1600000 or .60 * P = $1600000 $960,000 P =
Q Cash Salesof McDonalds customers amount to $1,200,000. TotalMcDonaldsalesare$1,600,000. Rate = Portion /Base Formula P R B Percentage Formula Solving forRate Whatpercentof customers pay cash? What do you have to find? $1,200,000/$1,600,000 R = 12/16 = .75 = 75% R=
Q 60%of total sales are from drive-thru customers . Sales of drive-thrucustomers are $960,000. Base = Portion /Rate Formula P R B Percentage Formula Solving for Base Whatare McDonald’s total Sales? $960,000 is 60% ofwhat total sales? What do you have to find? B= $960,000/ 60% $1,600,000 B=
Q 6% GST + 8% PST Calculate Percentage Formula Solving for Base You buy a new stereo in Ontario and pay a total of $649. This includes 6% GST and 8% PST . Find (a) the sticker price of the stereo before taxes, and (b) the amount of each tax. What do you have to find? The problem can be restated as: $649 is114%of the sticker price.
Q Statement: $649 is114% (or 1.14)of the sticker price. 1.14 = $569.30 Proof $34.16 GST $45.54 PST + $569.30 = $649 Percentage Formula Solving for Base You buy a new stereo in Ontario and pay a total of $649. This includes 6% GST and 8% PST. Find (a) the sticker price of the stereo before taxes, and (b) the amount of each tax. $649 (A) (B) $569.30 * 6% GST =$34.16 $569.30 * 8% PST =$45.54
Q 2,400,000 $ 800,000 $ 800,000 Percentage Formula Solving forRate of Percent Change If McDonald’s sales increase from $1,600,000 to$2,400,000, what is thepercent change? Initial(Base)Value $1,600,000 Final Value Base Method Difference % change = Difference Base % change = $1,600,000 = .5 or 50% Increase

Company Income Earners 8:00a Payroll Cheque 00001 Pay Pay Roll / $ Salaried Commissioned Hourly
8:00a Payroll Cheque 00001 Pay Pay Salaried Roll / $ • Receives an ANNUAL amount. • e.g. $50,000 per annum • May receive other incentive payments. • e.g. Year-end Bonus Usually paid Semi-Monthly or Bi-weekly
Commissioned 8:00a Payroll Cheque 00001 Pay Pay Roll / $ Receives a percentage of sales made. e.g. Personal Sales $250,000 @ 10% Commission May receive other incentive payments. e.g. Exceeding sales quota - $20,000 @ 3% Can be paid both a salary and receive commission. Can be paid Semi-Monthly or Bi-weekly.
Hourly 8:00a Payroll Cheque 00001 Pay Pay Roll / $ Where employees are paid on an hourly basis, for an agreed number of hours per day, and for an agreed number of days per week, then the employee is referred to a an hourly employee. In most cases this employee belongs to a recognized labour union, and wages are usually paid weekly.- May also receive ‘production bonuses’.
52 26 24 12 8:00a Pay Roll = $769.23 = $1,538.46 = $1,666.67 = $3,333.33
Hourly 8:00a Payroll Cheque 00001 Pay Pay Roll / $ Overtime If an hourly employee has to work more hours than the agreed number, then extra pay is rewarded to recognize this overtimeoccurrence. Theovertime rate is usually1.5 times the hourly rate
Q 8:00a Pay Roll $780.00 You are contracted to work a 40 hour week. Due to the illness of a colleague you have been required towork an extra 8 hour shift. You are paid $15.00 per hour with overtime at time and one-half. What is your Gross pay for the week? 40 @ $15.00 $600.00 Regular Hours worked 8 @ $22.50 180.00 Overtime Hours Overtime Rate = $15.00 * 1.5 = 48 $22.50
Q Calculation Commission 8:00a Payroll Cheque 00001 Pay Pay Roll / $ Larry is paid a straight commission of 8%. His computer net sales were $100,000. Larry’s draw was $750. How much commission is still due to Larry? Draw = An advance on future Commission earnings.
Q 8:00a Pay Roll $7,250 Larry is paid a straight commission of 8%. His computer net sales were $100,000. Larry’s draw was $750. How much commission is still due to Larry? Net Sales $100,000 * 8% = $8,000 Less:DRAW 750 Commission due to Larry
Commission 8:00a Payroll Cheque 00001 Pay Pay Roll / $ Variable Commission Scale This refers to the payment of different commission rates for various levels of sales.
Q 8:00a Commission Scale Pay Roll Up to$25,0005% $25,001 - $40,0007% Over$40,0018% Your car net sales were $120,000. Based on the Commission Scale, what are your gross commissions? $ Commission * .05 = $1,250 25,000 * .07 = 1,050 15,000 * .08 = 6,400 80,000 $8,700 120,000
Calculation Salary plus Commission 8:00a Q Payroll Cheque 00001 Pay Pay Roll / $ You receive a salary of $2,500 per month. In addition, you receive a 5% commissionfor sales over $15,000. Last month’s sales were $75,000. Calculate your gross pay.
You receive a salary of $2,500 per month. In addition, you receive a 5% commissionfor sales over $15,000. Last month’s sales were $75,000. Calculate your gross pay. 8:00a Q Pay Roll • $75,000 • 15,000 • $60,000 Gross Pay = Salary +Commission = $2,500+ ($60,000 * .05) = $5,500.
