There were approximately 11,000 students enrolled at Western Carolina last year. This figure goes up by about 225 students each year. Create an equation that can be used to find y, the total number of students, if x represents the number of years?

• y = 225x + 11,000

• y = 11000x + 225

• y = 225 - 11000x

• y = 225x - 11000

Ted's Taxi service charges a $5 pick up fee plus $2 per mile. What is the equation that can be used to find y, the total cost, if x represents the number of miles?

• y = 2x + 5

• y = 5x - 2

• y = 5x + 2

• y = 2x - 5

Kadi is starting a kayak rental company. She is going to charge $20 to rent the kayak plus $5 per hour of rental. What is the equation that can be used to find y, the total cost to rent a kayak, if x represents the number of hours rented?

• y = 5x + 20

• y = 5 + 20x

• y = 20x - 5

• y = 5x - 20

Alan buys a new car for $25,000. It depreciates at a rate of $2000 per year. What is the equation that can be used to find y, the value of the car, if x represents the number of years?

• y = 25000 - 2000x

• y = 25000 + 2000x

• y = 25000x - 2000

• y = 2000x - 25000

Suppose that the water level of a river is 34 feet and that decreases at a rate of 0.5 foot per day. Which equation can be used to find y, the water level, if x represents the number of days?

• y = 34 - 0.5x

• y = 34 + 0.5x

• y = 34x - 0.5

• y = 0.5x - 34

An attorney charges a fixed fee for an initial meeting and an hourly fee for all hours worked after this meeting. She charges $1750 for an initial meeting and $300 every hour worked. Create an equation that can be used to find y, the total cost of an attorney, if x represents the number of hours worked?

• y = 300x + 1750

• y = 300 + 1750x

• y = 1750x - 300

• y = 300x + 1750x

For babysitting, Nicole charges a flat fee of $3, plus $5 per hour. What equation can be used to find y, the total cost of babysitting, if x represents the number of hours she babysat?

• y = 3 + 5x

• y = 5 + 3x

• y = 3x - 5x

• y = 5x - 3

A plumber charges $25 for a service call plus $50 per hour of service. What equation can be used to find y, the total cost, if x represents the number of hours of service?

• y = 50x + 25

• y = 50 - 25x

• y = 25x + 50

• y = 50x - 25

Rufus collected 100 pounds of aluminum cans to recycle. He plans to collect an additional 25 pounds each week. Which equation can be used to find y, the total pounds of aluminum, if x represents the number of weeks collected?

• y = 100 + 25x

• y = 100x - 25

• y = 25 + 100x

• y = 25x - 100

• y = 20 + 30x

• y = 30x + 20x

• y = 20x - 30

• y = 30x - 20
