I think you're missing a bit of the question. If her savings can be modeled by x...?
Try this solution/explanation:
<u>way 1</u>:
rule: for an equation where no roots P+Q=0. It means, Px-Qx=0, ⇔ x(P-Q)=0, ⇔ P=Q.
for answer 'D' P=Q=15.
<u>way 2</u>:
rule: if an equation of the line has a form y=kx+b, then y₁||y₂ if k₁=k₂. It means, for y₁=Px-45 || y₂=Qx+75, then P=Q. P=Q, if 'D' answer.
Answer: D
The answer to your question is B.7/16.
The explanation for this is that 3/8 is in 16ths, 6/16, and 7/16 is greater than 6/16!
Hope this helps, if not, comment below please!!!
BG = 40. Equation: 4(3) + 8 + 20 = 40.
