Jan buys 1000 feet of cable. She splits it up into 25-foot sections. She gives 1/4 of that to a friend. She then puts half of the rest in storage. How much does she keep on hand?
assistant
How many sections does she get? ** She gets 1000/25=<<1000/25=40>>40 sections
How many sections does she give away? ** She gives away 40/4=<<40/4=10>>10 sections
How many sections does she keep? ** So she keeps 40-10=<<40-10=30>>30 sections
How many sections does she keep on hand? ** She keeps 30/2=<<30/2=15>>15 sections on hand
