Answer:
Explanation:
The linear function rule that models the total cost y (in dollars) for any number of sweatshirts x is:
y = 5.5x + 3.5
If the shipping charge applied to each sweatshirt, the linear function rule would change to:
y = (5.5 + 3.5) x
which simplifies to:
y = 9x + 3.5
The difference is that the constant term in the linear function rule changes from $3.50 to $9.00.
