Question

A small grocery store offers two different brands of milk.

Brand A 2% milk costs $3.50 a gallon.
Brand B whole organic milk costs $3.00 for a half-gallon plus a one-time deposit of $1.50 for the glass jug. Once the glass jug deposit has been paid, the jug can be brought back to the store and the deposit doesn't have to be paid for each additional half-gallon milk that is purchased.
Graph the cost of milk for the brand that is proportional.

PLEASE HELP ME ANSWER, BEEN AT IT ALL DAY PLEASE! THANKS! :3

Answer 1

Explanation:

So your question I confusing so i'm gonna put what i think this means $3 +$1.5=$4.5 if you take it back to store it will not have to be paid because it already is paid how much the price will be.

Answer 2

To find out which situation is proportional, graph each relationship on a coordinate plane and pick the one that goes through the origin, or (0,0).

Brand A 2% milk costs $3.50 a gallon. If 0 gallons of milk are purchased, the cost is $0. If 1 gallon of milk is purchased, the cost is $3.50. So, the ray representing the total cost of milk for Brand A will pass through the points (0,0) and (1,3.50).

Brand B whole organic milk costs $3.00 for a half-gallon, plus a one-time deposit of $1.50 for the glass jug. At 0 gallons, the cost is $1.50 for the deposit. At 0.5 gallons, the cost is $3.00 + $1.50, or $4.50. So, the ray representing the total cost of milk for Brand B will pass through the points (0,1.50) and (0.5,4.50).

Since Brand A goes through the origin, Brand A is proportional. The correct graph is shown below.
