When will the plans cost the same? Explain when each plan is a better option. Option 1: Plan A $39.99 for 200 min and $1.25 for each min after. Plan B $29.99 for 200 min and $1.50 for each min after. Option 2: Plan A $25.75 plus $.75 per min. Plan B $20.99 plus $1.00 per min Option 3: Plan A $39.99 plus $1.25 per min. Plan B $25.99 plus $1.75 per min Option 4: Plan A $45.99 for 400 min and $.50 for each min after. Plan B $49.99 for 400 min and $.40 for each min after MAT 144 Topic 5 DQ 2 In Chapter 1 of the text we looked at calculating a monthly payment for a loan. A related formula is to calculate the amount accruing when regular payments are made into an interest bearing account – often called the Savings Plan formula. (A is the accrued amount after t years of making regular payments, PMT, into an account at interest rate, r%, compounded n times each year.)

2. A(t) = PMT·((1 + r/N)N·t– 1)/(r/N) = PMT*((1 + r/N)^(N*t) – 1)/(r/N) The second version is essentially in the form used in Excel Suppose you want to buy a car and have decided that you can save $100 a month. Using information from an internet source, determine the current interest rate on savings accounts and use the information to answer the following: 1.How much money will you have saved in a year’s time? 2.How much will be interest? 3.Why wouldn’t a linear model work here? 4.Download Now
