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:

18 children

Step-by-step explanation:

Given

Required (missing part of the question):

Number of children that will be able to go to the zoo if 8 adult tickets are purchased

The graph is missing. However, the question can be solved without the graph.

From the question and equation, we can deduce the following:

So, when 8 adult tickets were sold.

This means

Substitute 8 for x in

Subtract 96 from both sides

Solve for y

This means that 18 children will be able to go

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
