To solve this question you need to make an equation including each variable: the extra $10, the $8 per hour (we'll represent hours as h) and the total amount of money, $66. Then simply solve the equation to get your final answer.
10 + 8h = 66 8h = 56 Subtract 10 from both sides h = 7 Divide both sides by 8
Factorize the numerator and denominator. You'll see that they both have a factor of 4 that can be canceled. The introduce a factor of 3 to change the denominator to 36.
