Carla is a waitress at Daybreak Diner, and she earns $5 for each hour she works. Last week, she earned $148 total, including $68 in tips. Write an equation that would represent how much Carla made last week with h, representing the hours she worked.
5h + 68 = 148

x = 0
r/4 - 12 = -5
r = 28
Ms. Chedraoui is a dog trainer. For each job she charges $100 for the first hour she works and $75 for each additional hour. Ms. C charged a total of $500 for a job on Sunday. Write an equation that can be used to determine h, the number of additional hours she worked on this job?
100 + 75h = 500
10 − 6v = −104
(HINT there is an invisible + sign in front of the 10!)
x = 19
-5 + 7k = -19
k = -2
Mr. Maldonado had a gift card with a $300 balance. He then bought several soccer jersey's for his team that cost $15 each. After the purchase, his gift card balance was $120. Which equation can be used to determine the number of Jersey's, j, he purchased?
300 - 15j = 120

x = 9
-12 = 24 + 4b
b = -9
Ms. C gave the class a gift card with a $100 balance. The class then decided to order pizza for $5 each. After the purchase, the gift card balance was $35. Which equation can be used to determine the number of pizzas, p, the class purchased?
100 - 5p = 35
−6 + a/4 = −5
a = 4
