Sylvia works at a car wash. She earns $50 per day and $12 per car washed. Sylvia wants to earn $158 in 1 day. What represents the number of cars Sylvia must wash to reach her goal?

**x = number of cars washed**

12x + 50 = 158 {she earns $12 for each car + $50 each day}

12x = 108 {subtracted 50 from each side}

x = 9 {divided each side by 12}

**She must wash 9 cars to reach her goal.**
