Thom’s restaurant bill is $45, and he leaves a 20 percent tip. what is the total cost for thom’s meal?

Total cost for Thom’s meal is $54

Step-by-step explanation:

We have been given that

Thom's restaurant bill = $45

He leaves 20% tip. Therefore, the amount of tip is given by

20 % of 45

= 45 × 0.20

= $9

Thus, he leaves $9 for tip.

Hence, the total cost of Thom's meal is

Restaurant bill + tip

= 45 + 9

=$54

Therefore, total cost for Thom’s meal is $54

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! )
