Question

Dolores deposited $2500 into a savings account which interest compounded monthly at a rate of 2.12%

How much interest will they earn after 8 years? Round to the nearest dollar


Help pleaseeeeeeeeeee

Answer 1

2961.63

Explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 2.12/100

r = 0.0212 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 2,500.00(1 + 0.0212/12)(12)(8)

A = 2,500.00(1 + 0.001766667)(96)

A = $2,961.63

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $2,500.00 at a rate of 2.12% per year compounded 12 times per year over 8 years is $2,961.63.
