A canoe rental service charges a $20 transportation fee and $30 dollars an hour to rent a canoe.  Write and graph an equation representing the cost, y, of renting a canoe for x hours. 

• y = $50x

• y = $20x + 30

• y = $30x + $20

• $30x + y = $20

Lee charges $3 for a basket and $2.50 for each pound of fruit picked at the orchard. Write an equation in y = mx + b form for the total cost of x pounds of fruit from the orchard.

• y = 3x + 2.5

• y = 2.50x + 3

• y = 2.50x 

• y = 3x + 2.50

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

• y = 12 + 325

• y = 12x  + 325

• y = 325 - 12x

• y = 325x + 12
