Using proportions, it is found that the life span of the person would be 14 years, 212 days and 22 hours shorter.
---------------------------
- 2 packs a day for 35 years is 40 cigarettes a day for 12775 days, as
. - Thus, a total of 511000 cigarettes, as
. - Assuming each cigarette costs 15 minutes of life, the person loses 7665000 minutes of life, as
- One year has 525600 minutes, thus the person loses 14 years of life, as
- Looking at the decimal part, the person loses 212 days of life, as
- Again looking at the decimal part, 22 hours, as
- Thus, the person loses 14 years, 212 days and 22 hours of life.

Step-by-step explanation:
the way to find how many participanted in the class voted, you need to look at the percentages and the number of students that voted for Vicky.
50% of students voted for Vicky and the question later explained that the total of the 50% was 30 students. This mean we know half of the student that participated. To find the total amount of students to make 100%, you need to multiple 30 by 2. which is 60.
Now that we know there were 60 students in total, we can find how many participated by using Iverson's percentage.
this is the formula that can help with any percentage math problem:
The percentage of something ÷ 100% = the number you are looking for ÷ the total
in our case:
40÷100 = x (because it is the unknown term)÷60
from here you cross multiple getting
2400÷100x
which equals
24
now we have to add Vicky's and Iverson's voter
24 + 30= 54
60-54=6
6 students did not participate
