Mark is buying supplies for his students. He is buying a notebook (n) and a pack of pencils for each of his 25 students. Each pack of pencils costs $1.25. If Mark’s total cost is $156.25, which of the following equations can be used to find how much each notebook cost? Select TWO that apply.

• 25(n) + 31.25 = 156.25

• 1.25(n) + 25 = 156.25

• 25(n) = 156.25 + 31.25

• 25(n) = 156.25 - 31.25

Marta used a coupon to save $3.50 on a book she bought. When Marta bought the book, she gave the sales clerk a $20.00 bill, the book, and the coupon. The sales clerk gave Marta $9.01 in change. Which of the following equations could be used to find, p, the price of the book before the coupon was applied?

• 20 − 9.01 = p

• 9.01 = 20 − p + 3.50

• 9.01 = 20 − p − 3.50

• 9.01 + 3.50 = p

Jacob is planning a trip to the amusement park. He has $25.00 to spend on his trip. The admission fee to the park is $15.75, and each ride at the park costs $0.50. He states that the inequality 15.75 + 0.50r ≤ 25.00 represents this situation, where r stands for the number of rides. Jacob determines that the solution to this inequality is r ≤ 18.5, and states that he can go on 19 rides at the amusement park. Explain the flaw in Jacob’s reasoning. If Jacob has $28.50 instead of $25.00, determine the maximum number of rides that Jacob can go on.
