Not sure of the answer but i know what factors
p ^2 - 2p
p (p-2)
-q^2 +2q
-q (q-2)
so maybe (p-q) (p-2) (q-2)
18 is the right answer. The two fractions must be porportional
Multiply 18 by12.50 =225
multiply 18 by 5 = 90
add 225+90=315
subbtract 350 from 315 =35
35 is how much she had left over
Answer #1: x= 250
50 = x times 20/100
X= 100 times 50/ 20
X=250
Answer #2: same explanation but the answer is X= 120
If your talking about merging the percentage of the answer, I can’t help you with that
