Question

On a recent trip to the convenience store, you picked up 4 gallons of milk, 4 bottles of water, and 8 snack-size bags of chips. Your total bill (before tax) was $25.20. If a bottle of water costs twice as much as a bag of chips, and a gallon of milk costs $1.50 more than a bottle of water, how much does each item cost?​

Answer 1

C = 20.25/27 = 75 cents for chips
W = 2C = $1.50 for a bottle of water
M =2.40+1.50 = $3.90 for gallon of milk
