Yaritza and her children went into a restaurant that sells hamburgers for $5 each and tacos for $2.50 each. Yaritza has $60 to spend and must buy at least 14 hamburgers and tacos altogether. If x represents the number of hamburgers purchased and y represents the number of tacos purchased, write and solve a system of inequalities graphically and determine one possible solution.

1. A system of inequalities that can be written to solve the problem is as follows:

5x + 2.5y ≤ 60
x + y ≥ 14
x ≥ 0, y ≥ 0

2. One possible solution within the shaded region could be x = 8 and y = 6.

We set up a system of inequalities to represent the constraints and then graph them to find a possible solution.

Let's start by defining our variables and setting up the inequalities.

Let x represent the number of hamburgers purchased and y represent the number of tacos purchased.

The constraints are:

Yaritza has 60 to spend, so the total cost of the hamburgers and tacos cannot exceed 60:

1) 5x + 2.50y ≤ 60

Yaritza must buy at least 14 hamburgers and tacos altogether:

2) x + y ≥ 14

Yaritza must buy at least 0 of each item:

3) x ≥ 0, y ≥ 0

We can graph these inequalities to find a possible solution.

Graph the line 5x + 2.50y = 60 by finding the intercepts:

When x = 0, 2.50y = 60, so y = 24

When y = 0, 5x = 60, so x = 12

We plot these points and draw the line.

Next, graph the line x + y = 14 and find the intercepts:

When x = 0, y = 14

When y = 0, x = 14

We plot these points and draw the line.

Finally, shade the region that satisfies all the inequalities.

Thus, one possible solution within this region could be, for example, x = 8 and y = 6, which satisfies all the constraints.
