Answer 1

Answer:

$52.5n+449.85$

Step-by-step explanation:

The cost is given for 1 sweatshirt. To find the cost of 15 sweatshirts, we need to multiply the expression by 15. Let's do this:

$15(3.5n+29.99)\\=15(3.5n+29.99)\\=15(3.5n)+15(29.99)\\=52.5n+449.85$

This is the expression that represents the cost of 15 sweatshirts.
