I could be wrong here but I’m pretty sure the answer is
P(0.15) because 0.75 x 0.2 is 0.15
X-4y=28
8x+4y=8
---------------
9x=36→x=4
4-4y=28→y=6
—-----------------------------------------------------------
y-5=x
4(y-5)-y=4
4y-20-y=4
3y=24
y=8
x8-5=3
27: C 28: B 29. A
And I kindly decline the marriage offer lol. If you need an explanation of how I did this then I will gladly do so they are pretty simple.
