Question

Melanie is investing $13, 336 into a savings account. The savings account earns a 1.5% interest rate compounded biannually

Answer 1

(Okay then to calculate this one we will take the 13336 and divide it by two because its a biannual interest rate, now we will multiple the resulting number with our interest rate since it's 1.5%,
so that would be 6668 * 1.5% which is actually equal to about 100.02, after calculating that we would times that number by two since this is a biannual interest rate, meaning that our interest rate is 200.04.
so Melanie's total savings would be 13536)

Hope that helps!~
