**Steve**, Tuesday, October 18, 2011 at 10:25amJust multiply by conversion factors to change from what you have to what you want:

You have

10.0 hp * 8.00 hr = 80.00 hp-hr * 0.0735$/kw-hr = 1088.435 $-hp/kw * 1.0 kw / 1.341 hp = $811.66

**drwls**, Tuesday, October 18, 2011 at 11:58amA. I get a different answer

10 hp = 7460 W = 7.46 kW

Energy used (in kW-h) = 7.46*8 = 59.68

Cost = (59.68 kW-h)*(0.0735 $/kW-h)

= $4.38
