Answer:
$125
Step-by-step explanation:
Since there are 12 months in a year, divide the total bill by the total number of months.
1500/12 = $125
Let the width be w, then length = 2w - 1
Area = length times width = w(2w - 1) = 21.
Thus, 2w^2 - w = 21 or 2w^2 - w - 21 = 0
Solving the quadratic equation gives that w = 3.5.
Therefore, width is 3.5 ft and length is 2(3.5) - 1 = 6 ft.
Just draw a line at the midpoint and a salon also if this helps OK
