1. In 1941 A. J. Liebling wrote in The New Yorker that Mr. Ormont, the manager of the Jollity Building, was paid $50 a week plus a commission of two percent of the rents. That commission earned him an extra two thousand dollars a year.

a. What was the average weekly rent on which Mr. Ormont's commission was based?

b. Do a linear equation for Mr. Ormont's weekly income. Identify the variables, slope, and intercept with their units.

c. What was his annual income in 1941?

d. What would Mr. Ormont's annual income be today adjusted for inflation? Use the inflation calculator found on the Consumer Price Index website to answer this question.

2a. Most of the world uses Celsius degrees when measuring temperature. Look up the formula for converting degrees Celsius (oC) to degrees Fahrenheit (oF) and write the formula in the space below. Is this a linear relationship?

b. Where would you like to visit outside of the United States?

c. Look up the temperature there in degrees Celsius. If you can't find the temperature there now, look up a typical or average temperature for that area.

d. Use the formula from part a to convert from degrees Celsius to degrees Fahrenheit.

e. Check this conversion using Google calculator or another online conversion calculator.

3. The table below shows the cost of renting a truck for one day in Boston in March of 2015. Four companies offer equivalent models.

Watertown U-Haul Budget Enterprise fixed cost 79 29.95 29.95 59.99 $/mile 0 1.39 0.99 0.59 a. Write a linear equation to represent what your total rental cost would be for each company. What does your variable represent with units? Identify the slope and the fixed cost with their units for each of your equations. b. Below is a graph comparing the rental cost per day. Write a detailed paragraph describing which rental company would be the cheapest.
