Topic: Mathematical Models

Sub Topic: Linear Models

Difficulty: Medium

Marks: 6

Question 2 is a fairly common style of Linear Models question. A linear model is presented for two companies that manufacture T-shirts. The linear models provide a rule for the total cost for manufacturing x number of shirts. There are 4 question parts (a-d), which ask questions related to the total cost for various manufacturing scenarios, and the number of shirts whereby the two companies have the same manufacturing costs.
