HELP PLEASE!!!! word problem?

Question

The number of students who smoke cigarettes at school is decreasing at a rate of one smoker every 4.36 days. At what rate in smokers per year is the number of smokers declining? Assume 365 days in a year and round to the nearest tenth of a smoker per year"

Answer 1

Take 365 and divide it be 4.36 days to get your answer.

Answer 2

365 days per year divided by 4.36 days tells you how many times the decrease of one smoker occurs. So 365/4.36=83.7155 rounded to the nearest tenth is 83.7
The number of smokers decline at a rate of 83.7 per year.

Answer 3

Okay, so in 4.36 days 1 person quits smoking and it takes another 4.36 days for another person to quit, etc. So what you really want to know is how many 4.36 day periods there are in a year.
Rather than give you the answer right away, instead of periods of 4.36 days which tend to complicate reasoning, think if instead it was 2 days, that is, after each two days a person stopped smoking, What you then want is how many two day periods in a year. Hopefully this helped you see that you divide 365 by two and get 182.5 periods. In the same way you divide 365 by whatever the period length is. In your problem it's 4.36, so divided 365 by 4.36 and round to the nearest tenth.

Answer 4

1 smoker / 4.36 days x 365 days / 1 year =
83.7 smokers / year =

the trick is to write your fractions and their units in such a way that all the units you do not need cancel and you are left with the units of your answer.
In your case they asked for the ratio of smokers per year
(smokers / year), so arrange the fraction's units to have smokers in the numerator and year in the denominator then just multiply or divide the numbers depending on where they are. Top you multiply and bottom you divide.

Answer 5

365/4.36=83.7 smokers per year
