4.75=4+0.75
0.75=0.75/1=7.5/10=75/100=3/4
4 and 3/4
28% decrease
Solution:
Calculate percentage change
from V1 = 25 to V2 = 18
(V2−V1)|V1|×100
=(18−25)|25|×100
=−725×100
=−0.28×100
=−28%change
=28%decrease
If p(x) is a function, then a real-world example might be
The amount of fish food, in grams required for the giant koi fish in the pond can be represented by the function

. If there are 50 fish, how many grams of fish food will you need?
