Answer:
$1,760
Explanation:
So I'm assuming the interest is simple interest rate which means that the interest applied each year is 12% of the original amount.
So this means that we can find the interest rate from one year by finding 12% of 800, and to do this we convert 12% to a decimal by dividing by 100 to get 0.12 and then use this decimal value to multiply by 800 to get: 0.12 * 800 = 96.
This means annually $96 will be charged in interest. To find how much interest there is after 100 years, simply multiply by 10, to get $96 * 10 = $960.
This is only the interest rate, it's like a fee, you still have to pay back the original amount, so all together you pay: $ borrowed + interest
So we add the interest rate 960 to the amount borrowed 800 to get: 960 + 800 = 1,760
