38
because since all abc and xy have the same coefficients it makes it easier.
i just made a=-2, b=-4,and c=4 because when added up it equals -2
i also made both x and y =5 becasue when added up it equals 10
so, -9(-2)+2(5)-9(-4)-9(4)+2(5)
18+10+36-36+10=38
I got it =4/5 hope it’s right
A + C = 90/190
B + D = 100/190
Therefore answer is H
1.15¹⁰=4.0456, the growth rate, so the increase is 3.0456 or 305%.
