Answer:
He will pay back $2030
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
