Sally deposited $4,000 in a certificate of deposit that paid 2.75% interest compounded annually. what was her balance after one year

$4,110

Step-by-step explanation:

In compound interest, Future Value formula is;

FV = PV (1+r)^n

PV= amount deposited in present value terms = $4,000

r = interest rate = 2.75% or 0.0275 as a decimal

n= total duration of investment = 1

FV = 4000*(1+0.0275)^1

FV = 4000*(1.0275)^1

FV = 4000 *1.0275

FV = $4,110

Therefore, her balance will be $4,110

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.
