Question

Please help me with this!!!

Answer 1

The easiest way to attempt such questions is to throw in some numbers and do trial and error.

The question is asking about the change in values $p$ depending on the change in $w$. So, let's play around with $w$.

Take $w=1$, then $p=-0.25\times 1+15=14.75$
Take $w=2$, then $p=-0.25\times2+15=-0.5+15=14.5$
Take $w=3$, then $p=-0.25\times3+15=-0.75+15=14.25$
.
.
.
Take $w=100$, then $p=-0.25\times100+15=-25+15=-10$

Notice how $p$ decreases in value for every increase in $w$?

Therefore, as $w$ increases, the value of $p$ decreases (always).
