Only 4,52 would be on the graph.
If she stated at week 0 with 32 dollars it would be:
0, 32
1, 37
2, 42
3, 47
4, 52
5, 57
6, 62
7, 67
and so on.

Answer:
![57.2\ g](https://tex.z-dn.net/?f=57.2%5C%20g)
Step-by-step explanation:
In this problem we have a exponential function of the form
![f(x)=a(b^x)](https://tex.z-dn.net/?f=f%28x%29%3Da%28b%5Ex%29)
where
f(x) is the remaining mass of the element in grams
x is the time in minutes
a is the initial value (y-intercept of the exponential function)
b is the base
r is the rate
![b=(1+r)](https://tex.z-dn.net/?f=b%3D%281%2Br%29)
In this problem we have
![a=210\ g](https://tex.z-dn.net/?f=a%3D210%5C%20g)
---> is negative because is a decay's rate
![b=(1-0.083)=0.917](https://tex.z-dn.net/?f=b%3D%281-0.083%29%3D0.917)
substitute
The exponential function is equal to
![f(x)=210(0.917^x)](https://tex.z-dn.net/?f=f%28x%29%3D210%280.917%5Ex%29)
For x=15 minutes
substitute in the function
![f(x)=210(0.917^{15})](https://tex.z-dn.net/?f=f%28x%29%3D210%280.917%5E%7B15%7D%29)
![f(x)=57.2\ g](https://tex.z-dn.net/?f=f%28x%29%3D57.2%5C%20g)
