Question

Gavin and Caleb go to the movie theater and purchase refreshments for their friends. Gavin spends a total of $22.25 on 2 bags of popcorn and 3 drinks. Caleb spends a total of $39.00 on 12 bags of popcorn and 4 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. Using these equations, determine and state the price of a drink, to the nearest cent.

Answer 1

Explanation:

Answer 2

Drinks = 6.75

Popcorn= 1

Explanation:

Let the popcorn = P

Let the drink = D

2*P + 3*D = 22.25 multiply this equation by 6

12*P + 4D = 39.00

12P + 18D = 133.5 Subtract these two equations

- 14D = - 94.50 Divide by -14

-14D/-14 = -94.5/-14 Do the division

D = 6.75

=========================

12P + 4D = 39 Substitute for D

12P + 4*6.75 = 39 Combine

12P + 27 = 39 Subtract 27 from both sides

12P + 27-27=39-27 Collect like terms

12P = 12 Divide by 12

12P/12 = 12/12

P = 1 Answer
