Answer 2

Calculation of Fabric Usage

The seamstress bought 51 meters of fabric to sew eight shirts and several dresses. She used 2 meters of fabric for each shirt and at least 2.5 meters of fabric for each dress. To determine how many dresses she can sew with the remaining fabric, we need to calculate the total fabric used for the shirts and subtract it from the total fabric purchased.

The total fabric used for the shirts can be calculated by multiplying the number of shirts (8) by the fabric used for each shirt (2 meters):

Total fabric used for shirts = 8 shirts * 2 meters/shirt = 16 meters.

To find out how much fabric is left for the dresses, we subtract the total fabric used for the shirts from the total fabric purchased:

Fabric remaining for dresses = Total fabric purchased - Total fabric used for shirts = 51 meters - 16 meters = 35 meters.

Calculation of Dresses that Can be Sewn

Since the seamstress uses at least 2.5 meters of fabric for each dress, we can calculate the maximum number of dresses she can sew with the remaining fabric by dividing the fabric remaining for dresses by the fabric used for each dress:

Number of dresses that can be sewn = Fabric remaining for dresses / Fabric used for each dress = 35 meters / 2.5 meters/dress.

To simplify the calculation, we can convert 2.5 meters to a decimal by dividing 5 by 10:

Number of dresses that can be sewn = 35 meters / 2.5 meters/dress = 35 meters / 2.5 meters/dress = 14 dresses.

Therefore, the seamstress will be able to sew 14 dresses with the remaining fabric.

Please note that the calculations provided are based on the information given and assume that the seamstress uses the exact amount of fabric specified for each shirt and dress.
