Answer: No

Step-by-step explanation:

X does not represent the cost of fabric. X represents the number of yards of fabric used.

15x + 250

Could be read as ($15 * # of yards) + $250

So she has to pay $15 per yard of fabric plus an additional $250 base amount for having them made and hung in the first place.

She could use an additional variable to represent the cost of fabric.

Example: Y

Y = 15x

Cost of fabric is equal to $15 per yard * # of yards.
