Write and solve the inequality for each word problem. Show work.

1. The waiter makes $10 per hour plus $65 in tips. He wants to earn AT LEAST $150. How many hours should he work?

2. Matteo was told he could spend AT MOST $80 to spend at the mall. He bought lunch for $25. He wants to buy phone cases for his friends. If the phone cases cost $5. How many phone cases can he buy?

Answer 1

Answer:

Step-by-step explanation:

1. $10x+65\geq 150$ and solve for x

$10x+65\geq 150$

-65             -65

$10x\geq 85$

/10      /10

$x\geq 8.5$ The waiter has to work at least 8.5 hours.

2. $5x+25\leq 80$ and solve for x

$5x+25\leq 80$

-25          -25

$5x\leq 55$

/5     /5

$x\leq 11$ Mateo can buy at most 11 phone cases.

Answer 2

11 phone cases !!! Hope this helps :)
