  1. Andy is climbing up a very steep mountain in Colorado. His decent can be described by the equation f = 14,114 – 2350h where f is the number of feet above sea level and h is the time in hours Andy has hiked from the top of the mountain. Explain why it does not make sense for h to equal 7 in this equation.
  1. Chris works after school making deliveries for a company in his hometown. He earns money according to the linear function m = 7d – 3, where d is the amount of deliveries Chris makes and m is the amount of money earned. Fill in the table below with 5 coordinate points that would be reasonable based on this situation.

  1. Tammy bought a relatively new car that had only 2,563 miles on it. She plans to drive the car about 10,000 miles per year. Sketch a graph of the linear function which inputs the amount of years Tammy has owned the car and outputs the amount of miles the car has been driven.

  1. The amount of new snow falling on Williamsport is described by the equation s = p + rh. In this equation, s stands for total snowfall, p is the previous snow on the ground, r is the rate of the current snowfall and h is the time, in hours, of the current snowfall. If after 5 hours of snow there were 2.5 inches of snow and after 9 hours there were 3.5 inches of snow, how much snow was on the ground before this storm began?
  1. The graph below shows the relationship between the gallons of gas remaining in a car, and the distance that it can travel. Approximate, as accurately as possible, the gas mileage on the car described below?

  1. Jim’s Workout Gym offers the following membership choices: one month for $32, two months for $39, six months for $67, or a year for $104. The cost follows a linear relationship. Write an equation that could be used to figure out the cost (C) of m months?
  1. Ethan has $11.00 in quarters, q, and dimes, d. Create an equation that could represent the number of quarters and dimes that Ethan has?
  1. The graph below displays the distance (d) of Jabrina from her friend Jared after some time (t). Describe how the distance between the two friends is changing over time.

  1. Fill in the missing value in the linear function table below.

  1. The graph below depicts the amount of money in Juliet’s bank account over a span of time. Describe in as much detail as you can, what is happening with Juliet’s money.

  1. The equation used to determine the price of a new LCD TV is 1.06(0.85c) = p, where c is the original cost and p is the price you have to pay after a discount and sales tax. How much money are you saving because of the discount if the original price for the TV is $600?
  1. A certain cell phone provider charges $40 per month plus $7.50 for each Gigabyte of data for each cell phone user in a family. Your mother used x Gigabytes of data, your sister uses twice as much data as your mom and you used twice as much data as your sister last month. If the family spent $92.50 on cell phones last month, how many Gigabytes of data did you use? Write an equation that can be used to determine your solution.
