Problem Statement:
There are two stores, each receiving 7128m of fabric. On average, the first store sells 264m of fabric per day, and the second store sells 297m. Determine which store sells all the fabric sooner and by how many days.
Solution Method:
- Calculate the days it takes for the first store to sell all the fabric by dividing the received fabric by the average daily sales of the first store.
- Similarly, calculate the days it takes for the second store to sell all the fabric by dividing the received fabric by the average daily sales of the second store.
- To find out which store sells all the fabric sooner and by how many days, compare the two results obtained. Subtract the smaller number from the larger one to get the desired outcome.
Answer:
The first store sells all the fabric in:
7128 : 264 = 27 (days)
The second store sells all the fabric in:
7128 : 297 = 24 (days)
So, the second store sells sooner and by how many days:
27 - 24 = 3 ( days )
Answer: 3 days
