Answer: $75
Step-by-step explanation: If interest earned on an account in 2 years is $15, then after 10 years, the interest would be $75.
We can know this because, if we divide $15 by 2, we get the amount of interest the account makes in 1 year.
15/2 = $7.50. The account makes $7.50 interest pear year.
We want to know how much interest the account will make in 10 years, simply multiply 7.50 by 10.
$7.50 x 10 = $75 in 10 years.
