Answer:
12a + 8c ≤ 72
Explanation:
Given information:
- $12 = Cost of one adult ticket.
- $8 = Cost of one child ticket.
- $72 = Maximum available money.
Define the variables:
- a = number of adult tickets.
- c = number of child tickets.
As the maximum available money to spend at the zoo is $72, the sum of the cost of the adult tickets and child tickets should be equal to or less than $72.
The inequality sign for equal to or less than is "≤". Therefore, the equation for this given scenario is:
12a + 8c ≤ 72
