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

• y=(18/2)x + 0
• y = 18x
• y = 2x + 18
• y = 18x + 2

You are visiting Houston, Texas and a taxi cab company charges a flat rate of $4.00 for using the cab and $0.95 per mile.  Write an equation to determine the cost when x miles is driven.

• y = .75x
• y = .95x
• y = .95x + 4
• y=4.95x

The number of trees and the number of apples are given in the table above.  Determine which statement below is correct.

• The table is not proportional because the unit rate is not constant.
• The table is proportional and the unit rate is 1/13
• The table is proportional and the unit rate is 13.
• The table is not proportional because it doesn't pass through the origin.
