For each situation below determine if both the changes in the two quantities and the two quantities are proportional. Between 2000 and 2005 the Burger Company's profit increased by $3, 500 per year. In 2000 the Burger Company's profit was $52,000. Determine if the change in the number of years since 2000 is proportional to the change in the Burger Company's profit. Explain your reasoning. Determine if the number of years since 2000 is proportional to the Burger Company's profit. Explain your reasoning. You are planning a trip to Las Vegas and need to rent a car.

Determine if the change in the number of miles driven is proportional to the change in the total cost of the rental car. Explain your reasoning. Determine if the number of miles driven is proportional the total coat of the rental car. Explain your reasoning. When baking chocolate chip cookies you need 3 cups of flour per cup of sugar. Determine if the change in the number cups of flour is proportional to the change in the number of cups of sugar. Explain your reasoning. Determine if the number of cups of flour is proportional to the number of cups of sugar. Explain your reasoning.Explanation / Answer
i) rate of change of profit = $3500 per year
proft increases by $ 3500 each year
In 2001 profit = 2000 + 3500 = $ 5500
So, change in profit/change in year = 3500
So, change in year = chane in profit/3500
It means change in year is dierctly proptional to change in profit.
ii) P(x) = 2000 + 3500*x where x is no of years since year 2000
So, x = ( P -2000)/3500
No. of years is proptional to profit
