The total cost for a bucket of popcorn and 4 movie tickets is 56 dollars The total cost for the same size bucket of popcorn and 6 movie tickets is 80 dollars The cost of a bucket of popcorn is 8 dollars Which equation represents the relationship between y , the total cost of the popcorn and movie tickets, and x , the number of movie tickets that are purchased?
Answer
A
y is equal to 14x minus 8
B
y is equal to 12x minus 8
C
y is equal to 12 x plus 8
D
y is equal to 14x plus 8
Explanation
The popcorn costs $8, so the 4 tickets cost $56 − $8 = $48. Each ticket costs $48 ÷ 4 = $12. For x tickets, the total cost is therefore y = 12x + 8, which is choice C.
