One of U.S. Shirt ’ s competitors, Hot Shirts, advertises that they make custom T-shirts for $5.50 each with a one-time set-up fee of $ Your boss brings you the advertisement from Hot Shirts and asks you to figure out how the competition might affect business. Hot Shirts Using Tables, Graphs, and Equations
Hot Shirts Using Tables, Graphs, and Equations Create a line graph of the data from your table. First, choose your bounds and intervals. Remember to label your graph clearly and add a title to the graph. Use your graph to determine the price of: 40 shirts 27 shirts Use your graph to determine how many shirts can be purchased for: $125 $570.
Hot Shirts Using Tables, Graphs, and Equations Write an algebraic equation for the problem situation. In this lesson, you have represented the problem situation in four different ways: as a sentence, as a table, as a graph, and as an equation. How are the representations connected?
Comparing U.S. Shirts and Hot Shirts In the last two activities you explored the costs of ordering T- shirts from two companies, U.S. Shirts and Hot Shirts. Your boss asks you to determine which company has the better buy for T-shirts in different situations. Using Tables, Graphs, and Equations
