Answer 2

Calculating the Price Difference for the Second Roll of Fabric

To calculate the price difference for the second roll of fabric, we can use the following formula:

Price Difference = (Cost of Second Roll) - (Cost of First Roll)

Given that the first roll is 18m and the second roll is 21m, and the second roll is 24 rubles more expensive than the first roll, we can calculate the cost per meter for each roll and then find the price difference.

Let's calculate the price difference using the provided information.

Calculation

First, we need to find the cost per meter for each roll.

For the first roll: Cost of First Roll = Total Cost / Length of Roll 1 Cost of First Roll = Total Cost / 18m

For the second roll: Cost of Second Roll = Total Cost / Length of Roll 2 Cost of Second Roll = Total Cost / 21m

Now, we can use the formula to find the price difference: Price Difference = (Cost of Second Roll) - (Cost of First Roll)

Conclusion

By using the provided information and the calculations, we can determine the price difference between the two rolls of fabric.
