He needs to find area of Roof, Floor then times height.
Answer:
Around x = 3 y = 6
Step-by-step explanation:
I'm not sure if you need to round to the nearest whole or hundreth or tenth
-6x + 6y =6
-6x + 3y = -12
You would multiply the bottom equation by -1 to make -6x a positive so you can eliminate it.
-6x + 6y = 6
6x + -3y = 12
Eliminate -6y and add 6y to -3y as well as 6 and 12.
0 + 3y = 18
3y = 18
divide both sides by 3
y = 6
now that you know the value of y it will be easy to find x :)
(1+0.19/12)^(12))-1) =0.20745
= 20.74%
rounded to nearest tenth = 20.7%
Answer is A
