Answer: False.
Step-by-step explanation:
At the rate of 10% interest per year on $5000, William would earn:
=> 5000 x 10/100 = $500 a year.
In three years William would earn:
=> 3 x 500 = $1500 in three years.
The interest William would earn in three years is $1500 which is higher than $1000 dollars.
