-Mike Spenslothas an unpaid balance on his credit card of $4384.76 -His card charges a rate of 19.50% per annum. -The payment was due on March 23rd.
His minimum payment is $50 or10% of the outstanding balanceWhich ever is the GREATER
What is the minimum balance he will have to pay? 10% of $4384.76 = $43.85 $43.85 is less than $50, SO… Minimum Payment = $50
What will his balance be on the 15th of April First, calculate how many days it will be from March 23rd & April 15th Include the 23rd & the 15th
31 Days in March31 – 23 = 9 15 days in April till the balance date 9 + 15 = 24 Days to calculate for
Next, convert rate to a decimal 19.50% = 0.1950
Now, as interest is calculated (usually) /annum… We need to adjust the equation from 1yr to 24 days
We use I=Prt So, I = ($4384.76) (0.1950) (24÷365) I = $56.22
To answer the question of “what would the balance be on the 15th of April”… We use A=P+I A = $4384.76 + $56.22 =$4440.98

Blogginsis buying a new flat screen TV from Future shop EXAMPLE The offer is, $989.95 – No $$ down and 4 “easy” payments of $265
What is the total cost of the TV on the payment plan? 4 x $265 = $1060
What is the different btwn the list price and what BlogginsPaid? $1060 – $989.95 = $70.05 = $70.05 of Interest over 4 months
What was the rate of interest? Simple Interest formula I = Prt
Except we switch it up We need to find the Rate r = tx I P
I = Prt $70.05 = (989.95)(r)( 4 ) 12 $70.05 = (989.95)( 1 )r 3 3 x $70.05 = 989.95r
r = tx I P • r = 3 x$70.05 • 989.95 • r = 0.212 • Convert 0.212 to % = 21.2%
21.2% • REALLY!
