Tickets to the zoo cost $12 for adults and $8 for children. The school has a budget of $240 for the field trip. An equation representing the
budget for the trip is 240 = 12x + 8y. Here is a graph of this equation.

The number of children that will be able to go to the zoo is 18.

"The missing question;

How many children will be able to go to the zoo if 8 adult tickets are purchased ?

The given parameters;

The equation representing the budget for the trip;

12x + 8y = 240

When 8 adult tickets are purchased, the possible number of children to be accommodated within the budget is calculated as follows;

12(8) + 8y = 240

96 + 8y = 240

8y = 240 - 96

8y = 144

Thus, the number of children that will be able to go to the zoo is 18.

Plot a graph

First, we need to determine the minimum and maximum values of x and y

For x:

Minimum = 0

For maximum; Let y = 0

Solve for x

For y:

Minimum = 0

For maximum; Let x = 0

Solve for y
