Question

Quizplus · Accepted Answer

We can use the formula for compound interest:

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

where:
A = final amount
P = principal (initial amount) = $3,000
r = annual interest rate = 4.2% = 0.042
n = number of times interest is compounded per year = 1 (annual compounding)
t = number of years = 35

Plugging in the values, we get:

A = $3,000(1+0.042/1)^(1*35)
A = $3,000(1.042)^35
A = $3,000(3.300400)
A = $9,901.20

Therefore, Janet's savings will be worth $9,901.20 at the end of 35 years.

The closest answer choice to this is C) $230,040.06. However, there seems to be a mistake in the answer choices as they are all much higher than the calculated value.
