Kate is planning to go to the state fair this weekend with her friends. Admission to the fair is $5. To ride the rides Kate need to purchase tickets. It cost $0.50 for each ride ticket. If Kate has $25, what equation could she use to find how many tickets she can purchase?

• 5 = 0.50t +25

• 25 = 5t +0.50

• 25 = 0.50t +5

• 25 = 0.50 t -5

Marcus is on a budget, each month he only allows himself to spend $60 at Caroline's Coffee Shop. His usual coffee order is $6 after tipping the barista. What equation could he use to find how many cups of coffee he can purchase?

Sam wants to purchase the new AirPods Max. He needs to save $600 for this purchase. Sam babysits to earn money and charges $15 an hour. If he already has $250, how many more hours will he need to babysit to reach his goal? What equation could he use?

• -15x - 250 = 600

• 250 = 15x - 600

• 15x - 250 = 600

• 15x +250 = 600
