Answer 5

The function p(x) = 2x +1 determines how many pizzas need to be purchased for an after school meeting, where x is the number of students at the meeting. The club leader uses r(p(x)) to find the amount of money to bring for the pizza purchase. The function r(x) = 4x − 3. Solve for how much money to bring when there are 9 students in the meeting.
A.) 19
B.) 33
C.) 73 <-----
D.) 84

Answer 6

to find the amount of pizzas, we plug in p(9)
we get p(9)=19
r(p(9))=r(19)=(4*19)-3=76-3=73
