A driving range charges $4 to rent a golf club plus $2.75 for every bucket of golf balls you hit. Write an equation that shows the total cost c of hitting b buckets of golf balls.

• c = 2.75b + 4

• c = 2.75b

• c = 4b- 2.75

• c = 2.75b - 4

For lunch, Amanda had a hamburger and potato chips. The hamburger totaled 325 calories and each chip had 12 calories. Write a liner equation to represent the situation.

• y = 12 + 325

• y = 325 - 12x

• y = 12x + 325

• y = 325x + 12

Asia is a salesperson for Quark Computer Company. Each month she earns $500 plus one-sixth of her sales. What equation represents this situation?

• y = 6x - 500

• y = 1/6x - 500

• y = 6x + 500

• y = 1/6x + 500

Belinda's car needed repairs. The mechanic charged him $140 for the parts and an additional $48 an hour for labor. What equation represents this situation?

• y = $140 - $48h

• y = $140h + 48

• y = $140 + $48h

• y = $140 - 48

Lee charges $3 for a basket and $2.50 for each pound of fruit picked at the orchard. Which equation represents this situation?

• y = $3 + $2.50p

• y = $3 - $2.50p

• y = $3p + $2.50

• y = $3p - $2.50

Mega middle school sells wrapping paper to raise money for student activities. The school keeps half of all the sales, minus $300 for prizes for top sellers. What equation represents the situation?

• y = $300s - 1/2

• y = 1/2s - $300

• y = $300s + 1/2

• y = $300 - 1/2s

Valley Video charges a $15 annual fee plus $3 per movie for rentals. Write an equation to represent this situation.

• y = $15 - 3m

• y = $15m + 3

• y = $15m - 3
