Answer:
- principal: $7000
- interest rate: 3%
Step-by-step explanation:
amount repaid = principal + interest
$7840 = principal + $840
$7000 = principal . . . . . . . . subtract $840 from both sides of the equation
___
I = Prt
840 = 7000·r·4
840/(4·7000) = r = 0.03 = 3%
The principal was $7000; the interest rate was 3%.
