In Exercises 33-11, use the four-step strategy to solve each problem. Use x, y, and z to represent unknown quantities. Then translate from the verbal conditions of the problem to a system of three equations in three variables.
On a recent trip In the convenience slow, you picked up1 gallon of milk. 7 bottles of water. and 4 snack-size bags of chips. Your total bill (before lax) was $17.00. If a bottle of water costs twice as much as a bag of chips, and a gallon of milk costs $2.00 more than a bottle of water. how much does each item cost?
