At 12pm a dealership sells at a price of $45/car. Give evidence to support or refute the claim that the change in the number of cars you can buy with $4,500 is approximately proportional to a small change in the price. 1)find a function that expresses the exact change in the number of cars in terms of the change in price.

2)use part 1) to compute enough difference quotients that suggest or refute a progression toward a limit.

3) Include units in all steps of your computations.

Your food costs are $5,500. your total food sales are $11,000. what percent of your food sales do the food costs represent?

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
