Question

An online clothing company sells custom sweatshirts. The company charges ​$4.99 for shipping plus ​$20 for each sweatshirt. Write a linear function rule that models the total cost y​ (in dollars) for any number of sweatshirts x.

Answer 1

20x+4.99=y

Explanation:

Each sweatshirt cost $20, but we don't know how many sweatshirts someone will buy so we use X, representing the amount of sweatshirts. There is a shipping charge of $4.99, so we have to add that to the cost of the sweatshirts. 20x+4.99. Y is the total cost.
