Scenario 1: Jim needs to buy x t-shirts for his club. He was quoted a price of $5 per shirt plus a $40 set up fee. The total cost of the t-shirts can be modeled by the expression 5x + 40.
Scenario 2: Ulga bought the same present for each of her 5 cousins. Each present cost x dollars, and the postage for each gift was $8. The total cost of the presents can be modeled by the expression 5(x + 8).
Are the expressions for the two scenarios equivalent? Explain how you know
