Question

DJ spent $227.40 on plumbing supplies. He bought pipe that cost $6.75 per foot and a wrench set that costs $45.15. How many feet of pipe did DJ buy?

Answer 1

to find the cost of the pipe you take $45.15 away from $227.40. This gives you $182.25. Let x equal the number of feet of pipe bought and form an equation using x:
6.75x=182.25
x=182.25/6.75
x=27 feet

Answer 2

27 feet. first u subtract 227.40-45.15 then u get 182.25 then divide that by 6.75 and get 27 feet.
