Answer:
50 stuffed animals and 22 mystery boxes.
Step-by-step explanation:
Firstly, we assign variables.
Let the number of stuffed animals be x and the number of mystery boxes is y
The probability of selecting a stuffed animal is x/72 while the probability is selecting a mystery box is y/72
Now, since the total probability can be 1:
This means that
x/72 + y/72 = 1 •••••••(i)
Answer: Growth factor will be 0.15 and percent increase will be 15%.
Step-by-step explanation:
Since we have given that
the exponential growth function

1) We need to find the growth factor :
As we know the formula for "Compound Interest ":

If we compare the formula with our given equation, we get

So, the growth factor is at the rate of 0.15.
2) Percent increase will be

Hence, growth factor will be 0.15 and percent increase will be 15%.
