He needs 35.5 feet long fist two life's are 7.3 feet long and 6.8 feet long. How much more rope does Robbie need

Answer :

Answer: 21.4 feet of rope

Explanation: Since Robbie needs 35.5 feet of rope you have to subtract what he already has from that. You can add the 7.3 and 6.8 and subtract that to get the feet of rope still needed.
7.3+6.8= 14.1
35.5-14.1=21.4
