Answer:

c) y=1/2x

Step-by-step explanation:

A direct variation is a linear function that is written in the form of y=kx, so from the options that we have we have to search for linear functions, that rules out option "A", and now that is written in Y=KX in option b we have a liner function that is written y=X+B which is a constant, so that wouldn´t be and option D is Y=k/x so that one is also wrong, our correct option would be y=1/2x

The answer is c) y=1/2x because a direct variation is in the formula b=ka where k is a constant.

In this problem, we let x be the number of half gallons of milk the store bought, and x-12 be the remaining half gallonsWe use the equation profit = revenue-cost
88.08=4.02(x-12)-2.60x88.08=4.02x-48.24-2.6x1.42x=88.08+48.24=136.32x=136.32/1.42=96Hence, the number of half gallons of milk the store bought is 96
