A jewelry salesperson earns a base salary of $200 a week plus 25% of all of her sales over $300. This situation can be represented by the expression: 200 + 0.25( x - 300 )

Which of the following describes the meaning of the variable "x" for this situation?

A:the total amount of sales
B:the total amount of salary earned
C:the amount of commission earned
D:the total amount of sales after the first $300

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )

where is the graph, sweetheart?

step-by-step explanation:

set the two equations for y equal to each other. solve for x. this will be the x-coordinate for the point of intersection. use this x-coordinate and plug it into either of the original equations for the lines and solve for y.
