Question

If each paper clip is 3/4 of an inch long and costs 0.02$ exactly enough paper clips are laid end to end to have a total of 36 inches. What is the total cost of these paper clips

Answer 1

4 paper clips make up 3 inches. (4 * 3/4 = 12/4 = 3)

36 / 3 = 12; meaning that 36 inches are made up of 12 three inch parts.

You would multiply 12 * 4 as there are 4 paper clips per three inch part. (12 * 4 = 48)

You have 48 paperclips, so now just multiply by the price of a paper clip. 48 * 0.02 = $0.96

Answer 2

Given : One paper clip is of length : 3/4 inch

We need to find how many paper clips will make up a length of 36 inch, if they are laid end to end.

36 inches contains : 36 × 4/3 paper clips

36 inches contains : 48 paper clips

Given that each paper clip costs : 0.02$

48 paper clips costs : 48 × 0.02$ = 0.96$

so, the total cost of paper clips = 0.96$
