In Exercises 3946, 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. The bar graph shows the average annual spending per person on selected items in 1980 and 2010. All dollar amounts are adjusted for inflation. Use this display to solve Exercises 3940.
