Adoughnut shop has a fixed cost of $124
per day and a variable cost of $0.12 per doughnut. find the total
daily cost of producing x doughnuts. how many doughnuts can
be produced for a total daily cost of $250?

At least 2084 doughnuts would have to be sold to produce $250

Step-by-step explanation:

124 divided by 0.12 equals 1033.33333333 but you cant sell a third of a doughnut so in order to make $124 you would have to sell 1034 doughnuts.

250 divided by 0.12 equals 2083.33333333 but again, you cant sell a third of a doughnut so in order to make $250 you would have to sell 2084 doughnuts.

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
