Jordan and sharla are saving money to go on a study abroad trip. they must provide a down payment of $650 to sign up for the trip, and they can pay the remaining balance later. jordan raises money by mowing lawns in his neighborhood and charges $25 per lawn. sharla raises money by selling handmade necklaces for $15 each. sharla raises less money than jordan does because sharla only has enough materials to make 40 necklaces. write two constraints to model the problem. let x represent the number of la wns lordan mows and y represent the number of necklaces sharla sells. (b) can sharla afford the down payment with the money she earns selling all her necklaces? explain your answer.

A) 25x+15y=650

25x+15(40)=650

Or it could be 25x=650 and 15y=650

B) No because she makes $15 for every necklace which she only has 40 necklaces 15x40=600

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

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
