Let s represent the number of sales, and t the total pay
the equation to represent this situation is t = 2s + 50
so set t to 100, and solve for s
100 = 2s + 50
50 = 2s
25 = s
you need to make at least 25 sales

Since
, we know that
follows a Poisson distribution with parameter
.
Now assuming
denote the mean and standard deviation of
, respectively, then we know right away that
and
.
So,
Answer:
10
Step-by-step explanation:
subtract 5y from both sides of the equation
$122.57 • 4 + $555.28 = $1,045.56
$136.71 • 4 + $585.34 = $1,132.18
$1,132.18 - $1,045.56 = $86.62
