Caroline and Ellie go to the movie theater and purchase refreshments for their friends.

Caroline spends a total of $141.75 on 14 drinks and 3 bags of popcorn.

Ellie spends a total of $84.00 on 7 drinks and 9 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 drink, to the nearest cent.

  14 d3 b141.75 $

2* (7d9 b84$   )

14 d18 b168 $

14 d3  b141.75 $

/(18-3)b168-141.75=26.25 $

                      15 b= 26.25$

 one bag of popcorn= 26.25/15=1.75 $

7 d9b=9*1.75=15.75 $84  $

7d+15.75$=84$

7d=84-15.75=68.25

one drink costs = 68.25/7=9.75≅9.8 $

step-by-step explanation:

if i remember correctly with perpendicular stuff you just take away the negative

if i put something wrong your not gonna like it so rather not say nothing.
