paper clips - 20 paper clips in a box: usage is 1 box 2 times a week.\nrubber bands - 2.5oz bags: usage is 1 bag every week.\nneedles - 100 needles in a box - usage is 1 box 3 times a week.\nupon 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
Explanation:
Step1: Determine weekly usage of rubber - bands
The original usage is 1 bag (2.5oz) every week.
Step2: Adjust for new bag size
Since new bags are 5oz and original bags are 2.5oz, the number of 5 - oz bags used per week is $\frac{1}{2}$ (because $2.5\times2 = 5$).
Step3: Calculate 8 - week usage
Multiply the weekly usage by 8 weeks. The number of 5 - oz bags used in 8 weeks is $\frac{1}{2}\times8=4$.
