You plan to go snowboarding. The resort charges $15 an hour in addition to $25 to rent a board. Write an equation that represents the cost to go snowboarding for the day.

• y=15x-25

• 15x+25y=100

• 25x+y=15

• y=15x+25

Jacob collects hats.  He has 6 hats already, and he collects 2 hats a week.

• y = 2x + 6

• y = 6x + 2

• y = 2x - 6

• y = 6x - 2

At Joe's Clown Car Rental Agency, renting a car costs $35 plus $0.75 for every mile it is driven. 

• y = x(35 + 0.75)

• y = 35x + 0.75

• y = 0.75x + 35

• y = 0.75(x + 35)
