It will cost amber an estimated $3,723 a year in tuition to attend her preferred college. she has been putting $350 a month in a savings account for the past 3 years. the account does not earn interest. her parents will add to her account by giving her half of what she has saved towards her college expenses. does amber have enough to pay for 4 years of tuition and additional expenses?

no; she needs to save an additional $2,292.
no; she needs to save an additional $1,908.
yes; she will have $4,008 for other expenses.
yes; she will have $477 for other expenses.

someone

Yes; she will have $4008 for other expenses.

Step-by-step explanation:

First you find out how much she saved by multiplying 350 by 36 as she saved for 3 years which is 36 months.

After that you need to work out the amount she needs in total for her tuition by multiplying 4 by 3723 which is the amount needed per year.

If her parents add to her account half the amount she saved that means that they give her an additional 6300 as that's half of 12600.

This means she has 18900 and if you take away 14892 you will be left with 4008 for expenses.

were is the equation

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
