Solve It! You want to buy a sofa that was marked down by $50 before the clearance discount was applied.
The furniture store may add the 5% sales tax before applying the additional discount, or it may add the sales tax after applying the additional discount. Which way is better for you, the customer?

Problem 4 Got It? A store is offering a 15% discount on all items. Also, employees get a 20% discount (20% off original price(s)). Write a composite function to model taking the 15% discount and then the 20% discount.

Let D(x) = cost after applying the 15% discount, E(x) = cost after applying the 20% employee discount, and x = cost of item(s). Then D(x) = 0.80x and E(x) = 0.85x. (E ◦ D)(x) = 0.68x.

Let D(x) = cost after applying the 15% discount, E(x) = cost after applying the 20% employee discount, and x = cost of item(s). Then D(x) = 0.85x and E(x) = 0.80x. (E ◦ D)(x) = 0.68x.

Problem 4 Got It? Reasoning: In the scenario above, which order of discounts results in a lower cost to the employee?

Taking the 20% discount first results in a lower price.

Taking the 15% discount first results in a lower price.

The total discounts are the same, so it does not matter which discount you take first.
