If you borrowed $1450 to buy a used car at a rate of 10% interest and planned on paying it back in 4 years, what is the total amount you would pay back?

He will pay back $2030

Step-by-step explanation:

Simple Interest = (Principal * rate * time) / 100

Principal = $1450, rate = 10% and time is 4 years

Substitute the above info into the formula to get the interest

SI = (1450 * 10 * 4) / 100

SI = 145 * 4

SI = $580

He will therefore pay back principal plus interest, which will be

$1450 + $580 = $2030
