Tony wants to build the longest rope he possibly can, so he collects all the rope in his home. He finds an 8-foot rope, a 20-foot rope, three 2 foot ropes, and a 7-foot rope. each knot between the ropes makes him lose 1.2 foot per knot. How long is his rope when he's done tying them all together?

How many feet of rope does Tony have? ** The combined length of all the rope is 41 feet because 8 + 20 + (2 x 3) + 7 = <<8+20+(2*3)+7=41>>41
How many feet does Tony lose from the knots? ** He loses 6 feet from the knots because 5 x 1.2 = <<5*1.2=6>>6
How long is his rope when he's done tying them all together? ** The final length is 35 feet because 41 - 6 = <<41-6=35>>35
#### 35
