Question

Dan is cutting 4.75 foot lengths of twine from a 240 foot spool of twine. he needs to cut 42 lengths, and says that 40.5 feet of twine will remain. show that this is reasonable

Answer 1

to find the ammount of twine left we subtract (twine used) from (total twine) or (total twine)-(twine used)=ammount left



so he must cut 42 legnths of rope  each legnth is 4.75 and this is taken from a
total legnth of 240 so
240-42(4.75)=amount left
42 trimes 4.75=199.5
240-199.5=40.5 left
