Avery and Annabelle go to the movie theater and purchase refreshments for their friends. Avery spends a total of $31.25 on 12 bags of popcorn and 2 drink.

Annabelle spends a total of $66.00 on 4 bags of popcorn and 8 drinks.

Write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink.

31.25=12p+2d and 66.00=4p+8d

Step-by-step explanation:

First, lets say popcorn is p and drinks is d.

Avery spends 31.25 dollars to buy 12 bags of popcorn and 2 drinks. The world problem basically explains it itself. 31.25=12p+2d.

Annabelle spends 66 dollars on 4 bags of popcorn and 8 drinks. Same thing for this, it would be 66=4p+8d.

P.S: if you want me to give you the answer, just write back in the chat. If you don't write back today, I probably won't get to you.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
