Jose receives a $10 gift card for downloading music and wants to determine how many songs he can purchase. each downloaded song costs $1.19. write and solve an inequality to determine how many songs jose can purchase. what does the solved inequality represent?

The number of songs that can be downloaded is 8.

> means greater than

< means less than

≥ means greater than or equal to

≤ less than or equal to

Gift card received ≥ (cost per song x number of songs)

$10 ≥ ($1.19 x s)

$10 ≥ $1.19s

s ≤ $10 / 1.19

s ≤ 8

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! )

5/12, or 5: 12
