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.

Answer:
Yes, y = x represents a proportional relationship and the constant of proportionality is
Step-by-step explanation:
<em>The Proportional is a relationship between two quantity one of them equals the product of the other and a constant, where this constant called the constant of proportionality </em>
- If x and y are proportion, then y = k x, where k is the constant of proportionality
- The proportional relationship represented graphically by a line passing through the origin point (0, 0)
Let us solve the question
∵ y = x
→ It the same as the form of the proportional equation above
∵ is a constant
∴ y is the product of x and constant
∴ y = x represents a proportional relationship
Substitute x by 0 to find y and show it represented by a line passing through the origin
∵ x = 0
∴ y = (0) = 0
→ That means point (0, 0) lies on the line which represents the equation
∴ The line which represents this relation is passing through the origin
∴ y = x represents a proportional relationship
∵ y = kx, k is the constant of proportionality
∵ y = x
∴ k =
∴ The constant of proportionality is
