You and your sister went to the store. Your mom gave you $35 to buy a few things. The store charges $4 an hour for parking plus
an additional one-time charge (flat fee) of $1.50 for the use of the shopping cart. You were at the store for 3 hours. Your total purchase of items was $15.00. How much change do you get back?
If x=n then it would have 2 solutions because it would be x^2 = c which has a positive and negative solution but idk if that is what you are asking for
