8. Lakeshia once rented 6 movies and 5 video games for a total of $44. The next month, she rented 2 movies and 3 video games for a total of $22. What is the cost per video game and the cost per movie?

Answer 1

Answer:

a. Hot dogs= 65, soda = 130

b. Movie =$2.75, video = $5.5

Step-by-step explanation:

a. Let the number of hot dogs sold be y, therefore the number of soda sold will be 2×y = 2y

y + 2y = 195

3y = 195

y = 195/3

y = 65

Hot dogs sold = 65

Soda sold = 65 × 2 = 130

b. Let movie be m, let video be v.

6m + 5v = 44 .......... equation 1

2m + 3v = 22 .......... equation 2

Multiply equation 1 by 2

Multiply equation 2 by 6

12m + 10v = 88

12m + 18v = 132

Subtract

12m + 10v = 88

-12m + 18v = 132

-8v = - 44

v= 44/8

v= $5.5

Cost per video game is $5.5

From equation 1,

6m + 5v = 44

6m + 5(5.5) = 44

6m + 27.5 = 44

6m = 44 - 27.5

6m = 16.5

m = 16.5/6

m = 2. 75

Cost per movie is $2.75.
