Answer:
The most number of pieces that Cheo can order is 11.
Step-by-step explanation:
Cost of ordering pizzas:
Flat fee(delivery) of $7.
Each pizza costs $11.
So the cost of ordering x pizzas: 7 + 11x
Cheo has a total of $132, which is the most she can spend.
What is the most number of pieces that Cheo can order?
The cost has to be less than 132. So
7 + 11x < 132
11x < 132 - 7
11x < 125
x < 125/11
x < 11.36
She cannot order 11.36 pizzas, it's either 11 or 12. 12 would cost more than 132.
The most number of pieces that Cheo can order is 11.
