Vincent and 2 of his friends go to tge movies. A ticket costs $7.75. They decided to split the cost of the popcorn. If they eacg spent $10.25, how much did the popcorn cost

$7.50

Step-by-step explanation:

In this scenario, we know that they all spent the same amount on the ticket, and the same overall amount. Therefore we first subtract the total from the ticket amount to know how much each of them spent on popcorn (assuming they didn't make any more purchases).

10.25 - 7.75 = 2.50

So we can see that each member spent $2.50 on popcorn. Since there are three of them (Vicent and 2 friends) we simply multiply this number by 3 to find the total amount of the popcorn.

2.50 * 3 = 7.50

Finally, we can see that the Popcorn was worth $7.50

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
