Answer:

Step-by-step explanation:

1. [tex]10x+65\geq 150[/tex] and solve for x

[tex]10x+65\geq 150\\[/tex]

-65             -65

[tex]10x\geq 85[/tex]

/10      /10

[tex]x\geq 8.5[/tex] The waiter has to work at least 8.5 hours.

2. [tex]5x+25\leq 80[/tex] and solve for x

[tex]5x+25\leq 80[/tex]

-25          -25

[tex]5x\leq 55[/tex]

/5     /5

[tex]x\leq 11[/tex] Mateo can buy at most 11 phone cases.
