Let x= number rows
Then x + 5 = number of seats per row
x(x+5) = 126
X^2 + 5x = 126
x^2 + 5x -126 = 0; now factor or use quadratic:
(x+14)(x-9) = 0; so the answers are either -14, or 9, and since -14 is not possible in this case because you can't have a negative number of rows, the answer is 9 rows.
Check work: number of rows = 9, number of seats per row = 9+ 5= 14, and 9 x 14 = 126
Hi!
Your answer would be: <em>About $46.58.</em>
Reason being:<em> She made about $25.92 on Friday, so subtract $25.92 from $72.50 and you get $46.58.</em>
Hope this helps!
Let me know if you need anymore help, I'd be delighted to!
<em>Yours truly,</em>

Step-by-step explanation:
We can simply divide 630 by 0.9 to find the value:
<em>Checking, if she goes for 700 sq ft at $0.90 per square feet, she would need:</em>
<em> 700 * 0.90 = $630</em>

Yes, that's the max, so 700 sq. feet apartment is what she can afford.
