Answer:
20%
Step-by-step explanation:
First, take $2,000, and $500.
Second, add $500 to both of them, according to the question.
Third, find out what percentage of $2,500 is $500.
Fourth, simply divide 2500 by 500, or 500/2500 for a fraction form of it.
Fifth, times the answer by 100, and turn it into a percentage by adding this to it: %
x^2 + x-72=0
x(x+1) =72
Distribute
x^2 +x = 72
Subtract 72 from each side
x^2 +x - 72 = 0
Now this is the equation we can factor
a,e,c,b,d
i think that is it but im not completly sure
