A caterer charges a setup fee of $50, plus $20 per person. how much will the caterer charge if 35 people attend the party, and the customer has a coupon for $100 off the total?

Setup fee=$50
If 35 people attend cost will be =$(50+35×20)

Since the customer has a$100 coupon he would have to pay $(750-100)=$650
