Answer:
Step-by-step explanation:
x decreased by 60% = (1-0.60)x = 0.40x
x increased by 80% = (1+0.80)x = 1.80x
First, I find it helpful to write the function myself.
There is a set fee of $120, and $5 per <em>n</em> badges.
<em />120 + 5<em>n
</em>
This is a basic model. Now we can see if any match.
f(n) = 5<em>n</em> + 120 matches.

Plant's height after 31 months:82 centimeters
<h3>How to find the height of the plant</h3>
The equation that can be used to find the height of the plant is given as
h = 52 centimeters + 1m
We have that the plant grows at 1 centimeter every month hence we have 1m in the equation.
Then the number of periods is m, Now we are to find the height in this period of time
h = 52 + 1*31
= 51 + 31
= 82
Hence the height after 31 months is given as 82 centimeters.
