Answer:
11.33
Step-by-step explanation:
First find the markup
8.80 * 25%
8.8 *.25 = 2.20

11*.03
.33
Add the tax to the new price
11+.33
11.33
The discriminant of this equation is 49. The solutions for this equation are x=2 and x=-
I hope that helps.
That would be A, 22/12 and 27/12
Y is increased by 6 because if you imagine x being 3 then y would = 16 but if you increase x by 3 making 6 then y would = 22 and 16 increased by 6 is 22
