Tickets to a zoo cost $12 for each adult and $8 for
each child. A family has $72 for the zoo trip.
• Use a for the number of adult tickets.
. Use c for the number of child tickets.
Write an equation for this relationship.

Answer :

Total amount =$72
Adult tickets = a ($12)
Child tickets =c ($8)
We know that if we add the total cost of the adult tickets and the child tickets, it adds up to $72. So the equation is:
72=12a+8c

Answer:

12a + 8c ≤ 72

Step-by-step 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
