Lori buys a $586 certificate of deposit (CD) that earns 6.6% interest that compounds monthly. How much will the CD be worth in 1

Alex777 [14]

Answer:

Step-by-step explanation:

This problem can be solved using the compound interest formula

$A= P(1+r)^t$

Given data

A, final amount =?

P, principal = $586

rate, r= 6.6% = 0.066

Time, t= 13 years

Substituting our values into the expression we have

$A= 586(1+0.066)^1^3\\\ A= 586*(1.066)^13\\\ A= 586*2.295\\\ A= 1344.87$

To the nearest cent the in 13 years the CD will be worth $1344.9
