Which expression shows the total cost (c) for the number of games (g) one bowls?

• c = 1.25g + 5

• c = 1.25g + 5g

• c = 5g + 1.25

• c = 6.25 + 1.25g

Steven’s new cell phone plan charges a flat monthly fee of $24. The plan allows an unlimited number of text messages, but each minute (m) used for phone calls costs $0.15.

Which equation most accurately represents the monthly cost (c) of Steven’s phone bill based on how many minutes talked?

• c = 24 + 0.15m

• c = 24(0.15m)

• c = 0.15 + 24m

• c = 0.15(24 + m)

Use the information to answer the question.

A ski resort charges Susan a flat fee of $65 to rent skis. It also charges her a daily rate of $22 for a ski lift pass to get skiers back up the mountain. Let d = the number of days a ski lift pass is rented.

If Susan is charged $175, which equation represents her situation?

• 175 = 65d + 22

• 175 = 65 + 22d

• 175 = 87d

• 175 = 22(d + 65)

Olivia and Darius purchase bagels for a group of friends. The cost of each bagel, including tax, is $1.25. They pay with a $20 bill and receive $8.75 in change.

Which equation can be used to determine the number of bagels, b, Olivia and Darius purchase?

• 1.25b + 8.75 = 20

• 1.25 + 8.75b = 20

• 1.25b + 20 = 8.75

• 1.25 + 20b = 8.75
