Solving Systems of Inequalities
The class president has asked you to make your
delicious cupcakes for the next student council
fund-raiser. With the fund-raiser fast
approaching, you have asked your friends to help
you out. Some friends will frost the cupcakes and
others will decorate the cupcakes. At most, 5
friends have agreed to help. Write and graph an
inequality that describes the number of friends
who can be assigned to each task if there are at
most 5 friends available.
(adapted from Walch TRB U2-139)
Write an inequality and graph the solution.
Solving Systems of Equations
At an Italian bistro, the cost of 2 plates of
spaghetti and 1 salad is $27.50. The cost for 4
plates of spaghetti and 3 salads is $59.50. Write
and solve a system of equations to find the cost
of
1 plate of spaghetti and 1 salad.

Tickets to the theater cost $12 for adults and $9
for children. A group of 15 adults and children
are attending the theater. If the total cost was
$153, how many adults and how many children
went?
Write an inequality and graph the solution.
Gisele runs a company that makes tablet
computers. Each tablet requires an employee to
assemble it and an employee to test it. There are
25 employees or fewer available, depending on
who is out sick or on vacation. Write an
inequality that represents the number of
employees Gisele has available to do the work
and then graph the solution.
At Binh’s Greenhouse in early spring, there are
many plants to repot. The plants have to be
watered after they’re repotted. If it takes Binh 5
minutes to repot and 2 minutes to water each
plant, and he has at most 2 hours before the
greenhouse opens, what inequality represents
the time Binh has to repot and water the plants
before the greenhouse opens? What is the graph
of the solutions?
