Answer 3

find the change the increase then express that as a percent of the original
the change is the difference between the old and the new
and percent means per 100
same as setting up the ratio change/original = percentage / 100

Answer 4

Let’s write small equation. Let x = percent, P = pants sold, and I= increase in pants sold.
\[P + Px = I\]\[P(1+x)=I\]\[1+x=\frac{ I }{ P }\]\[x=\frac{ I }{ P }-1\]\[x=\frac{ I -P }{ P }\]
Then plug in values P =25 and I =37
\[x = \frac{ 37-25 }{ 25 }\]
x=0.48
Just multiply by 100 to turn in percent.
