Identifying Proportional and Non- Proportional Relationships in Tables Lesson 3

You have been hired by your neighbors to babysit their children on Friday night. You are paid $8 per hour. Complete the table relating your pay to the number of hours you worked. Based on the table above, is pay proportional to hours worked? Yes, pay is proportional because every ratio of pay to hours is the same.

Determine if y is proportional to x. Justify your answer. 1. The table below represents the amount of snow fall in 5 counties (in inches) to hours of a recent winter storm. No, it is not proportional because you cannot multiply the time column by the same number each time to get snowfall.

Determine if y is proportional to x. Justify your answer. 2. The table below shows the relationship between cost of renting a movie to the number of days rent.

Determine if y is proportional to x. Justify your answer. 3. The table below shows the relationship between the amount of candy (pounds) bought and the total cost.

4. Randy is planning to drive from New Jersey to Florida. Randy recorded the distance traveled and the total number of gallons used every time he stopped for gas. Assume miles driven is proportional to Gallons Consumed in order to complete the table
