Members of a school boosters club want to sell at least 10 school jackets and at least
21 caps during a fundraiser to cover their regular club expenses. The club will make $14
for every jacket sold and $2 for every cap sold. The club also wants the total amount of
money earned to be at least $300.
Part A Write a system of inequalities that shows how many jackets and caps the club
members need to sell to meet the conditions described above. Let x represent the
number of school jackets sold and let y represent the number of caps sold.
Part B Graph the system of inequalities from Part A, shading in the region that
represents the possible solutions to the system of equations. Locate and label the
point b 14 , 35 g on the graph.
Part C Will the club meet its goal of earning $300 if it sells 14 jackets and 35 caps?
Explain how you know. How much above or below its goal will the club be?

You really need to know how to do it yourself. I can give you a hint.

x >= 10
y>= 21

14x + 2y >= 300 (for part C just substitute here)

so.. you have to graph
x = 10
y = 21
14x + 2y = 300
