  17. A customer went to a garden shop and bought some potting soil for $17.50 and 4 shrubs. The total bill was $53.50. Write and solve an equation to find the price of each shrub. • 4p + $17.50 = $53.50; p = $9.00 • 4(p + $17.50) = $53.50; p = $4.00 • 4p + 17.5p = $53.50; p = $2.49 • 4p + $17.50 = $53.50; p = $11.25

  23. John and 2 friends are going out for pizza for lunch. They split one pizza and 3 large drinks. The pizza cost $14.00. After using a $7.00 gift certificate, they spend a total of $12.10. Write an equation to model this situation, and find the cost of one large drink. • 3d + $14.00 – $7.00 = $12.10; $1.70 • 2d + $14.00 – $7.00 = $12.10; $2.55 • 3d – $14.00 + $7.00 = $12.10; $9.55 • 3d + $14.00 – $7.00 = $12.10; $1.90
