Harper deposited $110 into a savings account that earns 3.5% interest a year. The function (R)t models the amount of money Raymo

Answer:

A. $2.26

Step-by-step explanation:

An equation for Harper's balance can be written similar to the one written for Raymond's balance. It will be ...

H(t) = 110(1.035)^t

For t = 2, the two balances will be ...

H(2) = 110(1.035^2) = 117.83

R(2) = 110(1.025^2) = 115.57

The difference is ...

$117.83 -115.57 = $2.26

Harper's account will have $2.26 more.

_____

As a quick estimate or sanity check, you can see that Harper's interest rate is 1% more than Raymond's. So, in 2 years, he will earn a little more than 2% more on his investment than Raymond earns. 2% of $110 is $2.20, so the difference can be expected to be slightly more than this.
