Describe a situation you're familiar with where one thing changes in correlation with another, similar to how function values change with variations in the independent variable. State whether that situation is close to being linear, exponential, or neither in its pattern of change. Explain your reasons for choosing this classification.

Consider a shop that only sells one product: rice. For each kilogram of rice sold, a certain amount of revenue is received. Therefore, the relationship between the weight of rice sold and the amount of revenue received, is going to be a linear relationship. For example, if a kilogram of rice costs $1, then 10 kg costs $10, 100 kg costs $100, and so on. This proportion is maintained for all numbers, thus making it a linear relationship.
