Ms. Hernandez has $100 to spend on parking and admission to the zoo. The parking will cost $7, and admission tickets will cost %15.50 per person, including tax. Write and solve an equation that can be used to determine the number of people that she can bring to the zoo, including herself.

she can bring 6 people to the zoo, including herself.

Step-by-step explanation:

Let (x + 1) represent the number of people that she can bring to the zoo, including herself.

The parking will cost $7, and admission tickets will cost $15.50 per person, including tax. This means that the total cost of bringing x people including herself to the party would be

7 + 15.5(x + 1)

Ms. Hernandez has $100 to spend on parking and admission to the zoo. This means that

7 + 15.5(x + 1) = 100

7 + 15.5x + 15.5 = 100

15.5x + 22.5 = 100

15.5x = 100 - 22.5 = 77.5

x = 77.5/15.5

x = 5

x + 1 = 5 + 1 = 6

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
