A 120-V motor has mechanical power output of 3.00 hp. It is 94.0% efficient in converting power that it takes in by electrical transmission into mechanical power.

(a) Find the current in the motor.

I got the same answers,17.5 A, whether I used round conversion or whole decimal answers conversion from hp to watts but it keeps saying my answer is differ by 10%
