Question

Sara gives tennis lessons every Saturday. She charges $ 20 for adults, $ 6 for children, and $ 8 for racket rental. Last Saturday, she taught five adults and nine children, and ten people needed to rent rackets. How much money did Sara make on that day?

Answer 1

Let y = the amount of money Sara made on Saturday

y = 5(20) + 9(6) + 10(8)

y = 100 + 54 + 80

y = $234
