750 because she on average makes 3000 dollars a month, making her monthly profit 750 but if she needs to spend each month a 500 dollar more then she is only making 250 a month multiply 250 by 3 and she made 750
I think it would be 12.207… use the Pythagorean theorem (a^2+b^2=c^2) so 10^2+7^2 100+49=149 Then take square root of 149 to undo the the squaring of c and it should be around 12.207 :)
