Respuesta :

Answer:

cost of each bag of popcorn =  $7

and cost of each drink = $6.75

Explanation:

given data

Mason spends a total = $69.75

drink =  9 drinks

bag = 1

Cooper spends a total = $68.25

drink =  3 drinks

bag  = 7

solution

we consider here

cost of each bag of popcorn =  x

and cost of each drink = y

so we can write equation as

9x + 1y = 69.75         ..........................1

3x + 7y = 68.25            ..........................2

we will Solving the system of equation and we get

x = $7

y = $6.75  

so cost of each bag of popcorn =  $7

and cost of each drink = $6.75
