A sales associate in a department store earns a commission on each suit and each pair of shoes sold. One week, she earned $47 in
earnstyle [38]
3s + h = $47
7s + 2h= $107


3s + h =$47
3s - 3s + h = $47 -3s
h = $47 - 3s

7s + 2($47 - 3s) = $107
7s + 94 -6s = 107
s + 94 = 107
s +94 -94 = 107- 94
s = 13

3(13) + h = $47
39 + h =$47
39 -39 + h= $47-39
h = 8

Check
7s + 2h= $107
7(13) + 2(8)= $107
91 + 16= 107
107 = 107

She earns $13 per suit sold and $8 per pair of shoes sold.

The plot below shows the graphs of three functions, f, g, and h, all of which determine the population of three different cities
monitta

So, here we have an exponential function.

Remember that an exponential function has the form:

y=a(b)^x=a(1\pm\frac{r}{100})^x

Where a represents an initial amount, and r is the rate of this amount to change. (Increase, or decrease).

So, given that the population of City A in 2000 was 40 thousand people and the population increased by 13% each year, we can say that

\begin{gathered} a=40 \\ b=1+\frac{13}{100}=1.13 \end{gathered}

So,

f(x)=40(1.13)^x

For city B:

\begin{gathered} a=40 \\ b=1+\frac{16}{100}=1.16 \\ g(x)=40(1.16)^x \end{gathered}

But something different happens with city C. This is not an exponential function, this is a linear function.

So,

h(x)=40+10x
