Answer 2

Calculation of the Cost and Quantity of Satin

To calculate the cost and quantity of satin, we need to compare the prices and lengths of 5 meters of sateen and 4 meters of satin. Then, we can determine how many meters of satin can be purchased instead of 150 meters of sateen.

1. Calculate the cost of 5 meters of sateen and 4 meters of satin: - The cost of 5 meters of sateen is the same as the cost of 4 meters of satin.

2. Determine the quantity of satin that can be purchased instead of 150 meters of sateen: - To find out how many meters of satin can be purchased instead of 150 meters of sateen, we need to divide 150 by the length of 5 meters (the length of sateen in each piece). - 150 meters of sateen / 5 meters of sateen = 30 pieces of sateen.

Therefore, instead of 150 meters of sateen, you can purchase 30 pieces of sateen, which is equivalent to 120 meters of satin.

Please note that the prices and lengths mentioned in this response are hypothetical and may not reflect actual market conditions.
