Hi! This is due soon and I really need help. (-: Write an expression to represent the income of the fundraiser in the following paragraph

Write an expression to represent the profit of the fundraiser.

The varsity basketball team is selling t-shirts as a fundraiser. It costs them $100 to have the shirts professionally designed, and they have to pay $5 for each shirt. They plan on selling the shirts for $10 each.

I already got that the expression that represents the expenses of the fundraiser would be -5x+100. But I was kinda confused about the other ones :-/ Any help would be appreciated (-:
