To find:The proportional relationship between the cost and size of the cone, and the constant of proportionality.

Answer to Problem 22STP
The cost of the cone is not proportional to the size of the cone soconstant of proportionality does not exist.
Explanation of Solution
Given information: The different prices of smoothies to their size is shown in the below table.
Size (oz) | |||
Cost ($) |
Calculation:
Two quantities in which the ratio or rate is constant, then they are to be said proportional and if the rates are not constant, then the quantities are said to be non-proportional. The constant ratio which is defining whether the two quantities are said to be proportional or not is known as constant of proportionality.
The ratio of
To obtain the rate of
The ratio of
To obtain the rate of
The ratio of
To obtain the rate of
Therefore, the cost of the cone is not proportional to the size of the cone so constant of proportionality does not exist.
