Answer:

$800.

Explanation:

We have been given that Gene's deposit earns 2.8 percent simple annual interest. At the end of the year, the interest that is earned is $22.40. We are asked to find the amount of original deposit.

To find the original amount of deposit, we use simple interest formula:


I=Prt, where,

I = Amount of interest,

P = Principal amount,

r = Annual interest rate in decimal form,

t = Time in years.

Let us convert our given interest rate in decimal form.


2.8\%=(2.8)/(100)=0.028

Upon substituting our given values in above formula, we will get:


\$22.40=P*0.028*1


\$22.40=P*0.028


(\$22.40)/(0.028)=(P*0.028)/(0.028)


\$800=P

Therefore, the amount of original deposit was $800.
