Linear Real World Practice

Which equation represents this situation: Rocky's Canoe Rental charges a flat fee of $25 and $30 per hour?

Which equation represents this situation:

Pappy's Pizza charges $8 for a plain cheese pizza and $1.50 per topping.

For lunch, Amanda had a hamburger and some potato chips. The hamburger had 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

Cell Phone Company initially charges $15.00 for airtime usage plus $0.20 per minute. Determine an equation that can be used to calculate monthly cell phone bill.

• y = 0.20x + 15

• y =15 (0.20x)

• y = 15 + x + 0.20

• y = 0.20 + 15x

Cell Phone Company initially charges $15.00 for airtime usage plus $0.20 per minute. Determine an equation that can be used to calculate monthly cell phone bill.

• y = 0.20x + 15

• y =15 (0.20x)

• y = 15 + x + 0.20

• y = 0.20 + 15x

Scoots Inc. charges $20 to rent a moped for the day and $0.50 per mile driven

What is the b (y-intercept)?

• 20

• 0.50

Sonya has $40 in her lunch account and pays $2 each day to eat lunch.  Which equation can be used to find the amount of money Sonya has left on her account after x days?

• y = 40 + 2x
• y = 40 - 2x
• y = 2 + 40x
• y = 2 - 40x

Given the table, write the equation in the slope-intercept form.

• y = 1/3x + 6
• y = 3x + 6
• y = 2x + 6
• y = 1/2x + 6

Paul the plumber charges $25 for a service call.  He then charges $100 an hour.  Write a linear equation to model this situation.

• y = 100x
• y = 25x
• y = 25x + 100
• y = 100x + 25

Based on the table, write the equation in slope intercept form.

• y= 5x+5

• y=1/5x+5

• y=15x+5

• y=10x+5
