    x is the number of students, so x = 9. They're asking for r(p(9)).

    ok. sooo 9 = 4x − 3. 9+3=12 divide by 4 i get three. but its not one of the choices..... :/

    r(p(9)) means plug 9 into the p(x) equation. Then plug that answer into the r(x) equation. Start by finding p(9) by plugging in 9 for x in p(x).

    r(x) is just the amount of money total, not for each student

    p(x) = 2x + 1 Substitute 9 for x p(9) = 2(9) + 1

    @nerlineg you're not solving for x. You're replacing it with a number

    thats 19 @peachpi and that just gives you the amount of pizzas they need to order

    9*2+1 = 18+1 = 19

    2x +1 determines how many pizzas need to be purchased they need to know how much money needs to be brought in so, wouldnt you put in 9 in the second function ?

    p(9) = 19. Now you need to find r(19) so put 19 into r(x)

    @nerlineg does it grade it as soon as you put in the answer and hit submit?

    @nerlineg please show me how it looks when you change the x in r(x) to 19
