Solving Linear Relations Problems

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)

The Roaming Cell Phone Company charges $15.00 per month plus $0.20 per minute of airtime usage.  If Juanita uses x minutes of airtime, what is an equation that can be used to determine her monthly cell phone bill (C)?

• C = 0.20x + 15

• C =15 (0.20x)

• C = 15 + x + 0.20

• C = 0.20 + 15x

Bob has $150 in his savings account and saves $40 per month.

• y = 150 + 40

• y = 40x + 150

• y = 150x + 40

Easy Car Rental charges $8.50 an hour plus a rental fee of $25.50.

• y = 8.5 + 25.5

• y = 8.5x + 25.5

• y = 8.5 + 25.5x

• y = 8.5x + 25.5x

Write an expression for the following. Jerry has $20 and makes $7 per hour.

• y = 7x + 20

• y = 7 + 20x

• y = 20 + 7

• y = 20x + 7x

A man is climbing down from 100 feet high descending 30 feet per minute.

• y = 100 - 30x

• y = 100 + 30x

• y = 100x + 30

• y = 100x - 30
