A is the answer because divide 74.5 by 10 and get 7.45 then 7.45 times the X or number of boxes gets you the Y or the cost of the boxes.

5/25 = x/20
To solve a proportion cross multiply:
(5 * 20) = (25 * x)
Simplify:
100 = 25x
Divide both sides by 25:
x = 100/25
x = 4
Answer:
The first equation is a direct variation. This type of equation has a form that is "y = kx," in which k is the constant. Changing both sides by a common multiple will still lead to the equation being evaluated as true, since the values will both increase by that multiple.
