You are selling rings for $7 dollars each. You have been contacted by a customer in Alaska who wants to purchase several of these rings and wants you to ship them to her. It’s only going to cost you $5 to ship these items to Alaska. Suppose another company sells the same item but charges half of your price. However, if the customer buys from this company, she will be charged $20 in shipping costs. Write two equations to represent the customer’s total cost based on how many items she buys from each of the two sellers—you and the other company.

Question

You are selling rings for $7 dollars each.  You have been contacted by a customer in Alaska who wants to purchase several of these rings and wants you to ship them to her. It’s only going to cost you $5 to ship these items to Alaska. Suppose another company sells the same item but charges half of your price. However, if the customer buys from this company, she will be charged $20 in shipping costs.  Write two equations to represent the customer’s total cost based on how many items she buys from each of the two sellers—you and the other company.

I'm not exactly sure but here's my guess:

x stands for the number of items the customer buys and y stands for the total cost.

7x + 5 = y
3.5x + 20 = y

Is this right?  If not, what's it suppose to be?  Thank you!  (=
