Give the step-by-step reasoning process and then the final answer. 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?
User
She gets 1000 / 25 = 40 sections. She gives away 40 / 4 = 10 sections. So she keeps 40 - 10 = 30 sections. She keeps 30 / 2 = 15 sections on hand.
The final answer: 15.
