The simple interest on a loan of $200 at 10 percent interest per year is

To calculate the simple interest on a loan, you can use the formula:

[ text{Interest} = text{Principal} times text{Rate} times text{Time} ]

In this case:

– Principal = $200

– Rate = 10% = 0.10

– Time = 1 year

Plugging in the values:

[ text{Interest} = 200 times 0.10 times 1 = 20 ]

So, the simple interest on the loan of $200 at 10 percent interest per year is $20 per year until the loan is paid off.

The correct answer is: $20 per year until the loan is paid off.
