Answer:
$180.
Explanation:
First lets find the interest rate.
6.1 ÷ 100 = 0.061
0.061 x $200 = 12.2
based on the calculations, 12.2 is our interest rate in a year. Now lets find the interest rate in 15 years.
12.2 x 15 = $183
So $183 is our precise interest rate in 15 years, but lets round the interest rate to the nearest 10 dollars. Therefore, $180 is our answer.
