8. The high school soccer booster club sells tickets to the varsity matches for $4 for students and $8 for
adults. The booster club hopes to earn $200 at each match.
a) Write an equation to represent the amount the booster club would like to earn from ticket sales at each
match. Let s represent the number of student tickets and a represent the number of adult tickets sold.
4 s  8a  200
b) Find your intercepts (in coordinate notation) and graph the function.
Let the x-axis represent the student tickets and the y-axis represent the
adult tickets.
x-intercept: (50,0)
y-intercept: (0,25)
c) Interpret the y-intercept in the problem situation.
When 0 student tickets are sold, the booster club must sell 25 adult tickets to reach its goal.
d) Interpret the x-intercept in the problem situation.
When 0 adult tickets are sold, the booster club must sell 50 student tickets to reach its goal.
e) If 13 student tickets are sold, how many adult tickets must be sold to reach their goal?
4(13)  8a  200
They must sell 19 adult tickets to reach their goal.
52  8a  200
8a  148
Selling 18 adult tickets will only earn $196.
4(13)  8(18)  196
a  18.5
