An auto shop has a part that Clark needs for $80. Clark buys 7 of them and got a discount. If Clark only had to pay $439, how much was the discount?
What would the full cost of the parts be? ** Originally the car parts would be a total of 80*7 = <<80*7=560>>560 dollars.
How much was the discount? ** Clark got a discount for 560-439 = <<560-439=121>>121 dollars.
