As a salesperson, you are paid $92 per week plus $4 per sale. This week you want your pay to be at least $200. Write an inequality for the number of sales you need to make, and describe the solutions.

• 92 - 4s ≤ 200; s ≤ 26

• 92 + 4s ≥ 200; s ≥ 26

• 92 - 4s ≤ 200; s ≤ 27

• 92 + 4s ≥ 200; s ≥ 27

Tina plans on going bowling this weekend, and there are two bowling alleys in her town. The Bowling Pin charges $5 for shoe rental and $3.50 per game. The Alley Way charges $3 for shoe rental and $4 per game. Write an equation to show the break even point between the two bowling alleys, and then solve the equation.

• 5 + 3.5x = 3 + 4x, x = 4

• 5 + 3.5x > 3 + 4x,x = 1

• 5x + 3.5 = 3x + 4, x = 0.25

• 5x + 3.5 = 3x + 4 x = 2
