Emma and sydney go to the movie theater and purchase refreshments for their friends.

emma spends a total of $25.50 on 7 drinks and 2 bags of popcorn.

sydney spends a total of $52.50 on 5 drinks and 10 bags of popcorn.

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

using these equations, determine and state the price of a bag of popcorn, to the nearest cent.

25.50 = 7d + 2p

52.50 = 5d + 10p

These are the two equations we're going to use to determine the price of popcorn.

First we need to eliminate one set of variables. Let's eliminate the drinks.

127.50 = 35d + 10p

-367.50 = -35d + -70p

-240 = 0d - 60p

-240 = -60p

P = 4.00

So, popcorn is $4, right? Let's keep working on the problem so we can double check...

So, now let's add the $4 as the variable for P.

25.50 = 7d + 8

52.50 = 5d + 40

17.50 = 7d

12.5 = 5d

d = 2.5

d=2.5

This checks out! Since both equations state that drinks are 2.50, that means we have the right pricing for popcorn... $4.00

Popcorn is $4.00, drinks are $2.50

Hope I could help! :)
