Question

An online company clothing company sells custom sweatshirts. The company charges $6.50 for each sweatshirt and a flat fee of $3.99 for shipping. Write a linear function in the form `y=mx+b`that represents the total cost, y, in dollars, for a single order of x sweatshirts.

Answer 1

y = 6.5x + 3.99

Explanation:

Let

Total cost = y

Single order of sweatshirts = x

Each sweat shirt = $6.50

We are given the linear function =

y = mx + b

Hence:

y = $6.50 × x + $3.99

y = 6.5x + 3.99

Therefore, the linear function in the form y=mx+b that represents the total cost is given as:

y = 6.5x + 3.99
