Question

Paper clips - 20 paper clips in a box: usage is 1 box 2 times a week. Rubber bands - 2.5oz bags: usage is 1 bag every week. Needles – 100 needles in a box – Usage is 1 box 3 times a week. Upon re-ordering supplies, only 5oz bags of rubber bands were available. How many 5oz bags of the rubber bands will be used in 8 weeks?

Answer 1

To find out how many 5oz bags of rubber bands will be used in 8 weeks, we divide 8 weeks by the number of weeks a 5oz bag lasts (2 weeks), resulting in a total of 4 bags needed.

Step-by-step explanation:

The question requires us to calculate how many 5oz bags of rubber bands will be used in 8 weeks, given that the normal usage is 1 bag of 2.5oz every week. Since only 5oz bags are available, we need to adjust our usage rate to match the new size. One 5oz bag is equivalent to two bags of 2.5oz, meaning that one 5oz bag will last for two weeks. Therefore, for an 8-week period, the calculation would be as follows:

1. Determine how many weeks a 5oz bag will last: 5oz / 2.5oz per week = 2 weeks per bag.
2. Calculate the number of bags needed for 8 weeks: 8 weeks / 2 weeks per bag = 4 bags.

Thus, the student will use 4 bags of 5oz rubber bands over the course of 8 weeks.
