2) Some restaurants hire people whose only job is to walk on the street and hand out free
samples. Of course, not every passerby takes the sample, but an average of 6 people per
half hour does. Suppose Ryley is partway through their shift of handing out the free
samples and has given out 14 samples so far.

a) Write an explicit formula for 𝑃𝑛, the number of free samples handed out after n halfhours.

b) If Ryley has 4 hours remaining in their shift, how many samples would they expect to
have given out by the time they get to go home?

c) Suppose Ryley, instead of a shift of a certain length of time, has to keep working until
they give away 50 free samples. How much more time does Ryley figure they have
to stay at work today?

Question 1193056: An important quality characteristic for softdrink bottlers is the amount of softdrink injected into each bottle. In a particular filling process, the number of ounces injected into an 8-ounce bottle is approximately normally distributed with a mean of 8.00 ounces and a standard deviation of 0.05 ounce. Bottles that contain less than 7.90 ounces do not meet the bottler's quality standard. If 20,000 bottles are filled, approximately how many will meet the quality standard?
