A. machines allow the same number of workers to check more products
Answer:
$8750.87
Explanation:
This is compound interest problem. The formula used to solve this would be:

Where
F is the future value (what we want, after 3 years)
P is the initial value (given 6900)
r is the rate of interest per period
here, 8% per year, so 8/4 = 2% per period (since compounded per quarter)
t is the time (3 years and compounding per year so times of compounding is 3*4 = 12), so t = 12
Substituting, we get our answer:

<u>There will be about $8750.87 at the account at the end of 3 years!</u>
