This will give you a little extra chairs but they have to be equal in each row

The cost equation has a constant rate of change, so this is a line of the form:
y=mx+b, you are told that there is a flat fee of $5 and an hourly rate of $2 so
y=2x+5
The y-intercept (the value of y when x=0) is 5. The point (0,5) on the line.
X,=-(5±✓25-36) ,/ 2
x={-5±✓-11)/2
x= -5/2 ± i✓11/2
