Consider the two savings plans below. Compare the balances in each plan after 7 years. Which person deposited more money in the​ plan? Which of the two investment strategies is​ better?

Yolanda deposits ​$550 per month in an account with an APR of 6​%, while Zach deposits $ 7000 at the end of each year in an account with an APR of 6.5

What is the balance in Yolanda's savings plan after 7 years?

To calculate the balance in Yolanda's savings plan after 7 years, we need to use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit)
r = annual interest rate (in decimal form)
n = the number of times that interest is compounded per year
t = the number of years the money is invested for

In this scenario:
P = $550 (monthly deposit)
r = 6% APR = 0.06 (annual interest rate in decimal form)
n = 12 (monthly contributions, or compounding frequency per year)
t = 7 (number of years)

Calculating the balance after 7 years for Yolanda's savings plan:

A = 550(1 + 0.06/12)^(12*7)

A = 550(1.005)^84

A ≈ $53,451.81

Therefore, the balance in Yolanda's savings plan after 7 years would be approximately $53,451.81.
