Answer:
6 * p ≤ 30
p ≤ 5
The maximum number of pies she can buy is 5
Step-by-step explanation:
Let p equal the number of pies she will buy
Each pie costs 6 dollars. She will spend 6 * p
The cost must be less than or equal to 30 dollars
6 * p ≤ 30
To solve divide each side by 6
6 * p/6 ≤ 30/6
p ≤ 5
Y: x-1 that is the answer. I think so.
