Which system models the problem below?
During the pandemic, Siobhan began making art on commission. They offer paintings in two sizes: Small (4 inch by 6 inch) and Large (8
inch by 10 inch) Each small painting takes approximately 3 hours and Siobhan charges $35 per piece. Each large painting takes them 5.5
hours and they charge $65 per piece. In February, they created 14 paintings and made a total of $760. How many paintings of each size
did they create in February?
X+ y = 14
a
3x + 5.5y = 760
35x + 65y = 760
O
35x + 65y = 14
3x + 5.5y = 65
3x + 5.5y = 65
35x + 65y = 760
X + y = 14

step-by-step explanation:

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

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
