Answer 1

Answer: She will earn $352.92 as interest.

Explanation:

Formula for compound interest
`= P((1+r)^t-1)`

, where P= principal value, r = rate of interest(in decimal) , t= time

As per given , we have

P = $2,500

r = 4.5% = 0.045

t= 3 years

then, Compound interest =
`2500((1+0.045)^3-1)=2500((1.045)^3-1)`

`=2500(1.141166125-1)=2500(0.141166125)\\\\\approx\ \$352.92`

Hence, she will earn $352.92 as interest.
