Work Step by Step

Because you work 3 hours at one job plus another 6 hours at a different job and have an additional 20 dollars for an allowance, we are able to create an equation with this given information. h: represents the amount you get paid per hour. 3h + 6h + 20 = 92 Add the two h terms: 9h + 20 = 92. Subtract 20 from both sides: 9h = 72 Divide both sides by 9 to get h by itself. h = 8
