Demand A hardware retailer wants to know the demand y for a tool as a function of price x. The monthly sales for four different prices of the tool are listed in the table.
Price, x | $25 | $30 | $35 | $40 |
Demand, y | 82 | 75 | 67 | 55 |
(a) Use the regression capabilities of a graphing utility or a spreadsheet to find the least squares regression line for the data.
(b) Estimate the demand when the price is $32.95.
(c) What price will create a demand of 100 tools?
