pietro wants to buy 4 t-shirts at $15 each and 3 pairs of
pants at $15 each. he has $35. how much more money
does pietro need to buy all the items?

a. $70
b. $65
c. $140
d. $85

A:$70

Step-by-step explanation:

15 times 4 which is 60

15 times 3 which is 45

60+45=105

105-35=70

$70

Step-by-step explanation:

First you have to know how much the pants and T shirts cost. So for the T shirts since they are 15 dollars each and he wants 4 do 15 times 4 which is 50 dollars. Then for the pants since they are 15 dollars each and he wants 3 that is 45 dollars. Add them both together and you get 105 dollars. Then get the amount of money he has and subtract that by the cost of all of it, which is $70.

I hope I helped you :)

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

29–30 . . . . . . . . . . . . 0.001005

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

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
