Asports club needs to raise at least $500 by selling chocolate bars for $2.50 each. sebastian wants to know how many chocolate bars, c, the sports club must sell in order to reach its goal.

Step-by-step explanation:

The sport club needs $500. We know that each chocolate bar costs $2.50. So, we just have to express this situations and solve.

Where is the amount of chocolate bars.

Solving this equation, we have:

Therefore, the sports club needs to sell 200 chocolate bars to reach $500.

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! )

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
