Question

Carrie's Catering is having a special on their box lunches. The minimum purchase is 14 boxes for $126. Each additional box is $7. If x represents the number of boxes over the minimum, which of the following equations represents the cost of box lunches during this special? A. y = 126x + 7 B. y = 126x - 7 C. y = 7x + 126 D. y = 126 - 7x

Answer 1

Since the minimum purchase is 14 boxes for $126, we know that when x = 0, the cost is $126. This eliminates options B and D.

For each additional box, the cost increases by $7. This means that for each additional box (x), the cost increases by 7x. Therefore, the correct equation is:

y = 126 + 7x

This equation is equivalent to option A:
y = 126x + 7.

So, the answer is A.
