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. Ask the House
