Use the graph to complete parts (a) and (b) below. 800- 700- Predicted Price 3.20 +0.150 Sqft 600- 500- 400- 300- 200- 100- 1500 2000 2500 3000 3500 4000 4500 Area a. Using the graph, estimate the predicted price for a home with 3000 square feet. The price for a home with 3000 square feet is about $ thousand. (Round to the nearest ten as needed.) Price (thousands of dollars)

Please answer with a neat presentation, so that it's easy to read. Also, if you can show your work so that I can see how to do the current and future problems like this. Thank you.

Consider the variation of temperature with altitude depicted in the graph below.   What is the “y-intercept”?

On the following graph, use the green point (triangle symbol) to plot the weekly total revenue when the market price is $50, $75, $100, $125, $150, $175, and $200 per scooter. TOTAL REVENUE (Dollars) 2610 2430 2250 2070 1800 1710 1530 1350 1170 990 0 25 50 75 100 125 150 175 200 225 250 275 300 325 PRICE (Dollars per scooter) Total Revenue ? According to the midpoint method, the price elasticity of demand between points A and B is approximately 0.69 Suppose the price of scooters is currently $125 per scooter, shown as point A on the initial graph. Because the demand between points A and B is Inelastica $25-per-scooter decrease in price will lead to a decrease in total revenue per week. In general, in order for a price decrease to cause a decrease in total revenue, demand must be Inelastic
