Marta estimates that the fixed costs associated with opening her new hair salon are $100,000. she expects the salon to attract 500 new customers in the first year, each of which will cost $25 to service. marta expects to generate $50,000 per year in revenue. for marta, the total cost of opening her hair salon and staying in business for one year will be

Marta expects $50,000 in revenue, but that's not cost, so we can nevermind that.

the "fixed cost" namely overhead just to open the doors is $100,000.

she's expecting 500 folks, each will incur costs of $25 a pop, so for all 500 that'd be 500* 25 or 12500 total.

so Marta's total cost is the overhead and 25 per 500 folks, namely 100,000 + 12500 = 112,500.

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
