Answer:
22x + 100 = 25x + 70, 10 yards
Step-by-step explanation:
Set the number of square yards of carpeting as x.
So, the cost of Country Carpets is: 22 * x + 100
And the cost of City Carpets is: 25 * x + 70.
In order for the costs to be the , the equations need to be equal.
22x + 100 = 25x + 70
Subtract 22x from both sides.
100 = 3x + 70
Subtract 70 from both sides.
3x = 30
x = 10
10 square yards
