    Answer:

    Cost = 52.5n + 449.85

    Step-by-step explanation:

    Given

    Cost = 3.5n + 29.99

    Required

    Determine cost of 15

    Cost = 3.5n + 29.99

    The cost of 15 sweatshirts is calculated by multiplying the cost of 1 by 15.

    So, we have:

    Cost = (3.5n + 29.99) * 15

    Open Brackets

    Cost = 3.5n * 15 + 29.99 * 15

    Cost = 52.5n + 449.85

    Hence, the simplified cost of 15 sweatshirts is

    Cost = 52.5n + 449.85
