Question

The cost (in dollars) of a custom-made sweatshirt is represented by $3.5n+29.99$ , where $n$ is the number of different colors in the design. Write a simplified expression that represents the cost of 15 sweatshirts.

Answer 1

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

$Cost = 52.5n + 449.85$
