Question

Joey invests in a CD where he will earn 5.5%

simple interest. If he deposits $1,400 in the
account, what will his total, including the
interest, be after 6 months?

Answer 1

You need to find the interest earned first
I=PRT
I=1400*0.055*0.5
I=$38.50
Now add the principle and the interest
$1400+$38.50
$1438.50
