Question

Harry owes the bank money. To repay his debt, he paid $150 back to the bank each month. After 10 months, his remaining debt was $6900. What was the original amount of Harry's debt?

Answer 1

$8400

Explanation:

150 x 10 = 1500

$1500 + $6900 = $8400

Answer 2

Answer: The original amount of his debt was $ 8,400

Explanation:

Hi, to answer this question we have to write an equation

The original amount of his debt (x) minus the product of the amount he paid per month (150) multiplied by the number of months he paid (10) will be equal to the remaining debt (6900).

Mathematically speaking:

x - (150 x 10) = 6900

Solving for x:

x- 1500 =6900

x = 6900+1500

x = $8,400
