Mike sells calculators. his competitor sells a new calculator line for $14 each . mike needs a 40% markup on selling price to make his desired profit and must meet price competition. what cost can mike afford to bring these calculators into the store? what is the dollar markup?

cost to afford to bring these calculators is $8.4

markup on retail = 5.6

Step-by-step explanation:

given data

selling price = $14

mark up on selling = 40%  = 40/100 = 0.40

to find out

What cost can Mike afford to bring these calculators

solution

we calculate markup on retail that is mark up on selling of selling price

markup on retail = 0.40 × 14

markup on retail = 5.6

so

cost to afford to bring these calculators = 14 - 5.6

cost to afford to bring these calculators is $8.4

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:  

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

30–31 . . . . . . . . . . . . 0.001037

white males

29–30 . . . . . . . . . . . . 0.001372

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

29–30 . . . . . . . . . . . . 0.001477

30–31 . . . . . . . . . . . . 0.001503

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
