Autility company charges $.12 for each kilowatt-hour of electricity you use. your electric bill was $125.10. how many kilowatt-hours did you use?

1042.50 kilowatt-hours

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
