Grant Corporation manufactures a drink bottle, model CL24. During 2020, Grant produced 240,000 bottles at a total cost of $1,080,000. Wren Corporation has offered to supply as many bottles as Grant wants at a cost of $4.40 per bottle. Grant anticipates needing 255,000 bottles each year for the next few years. Read the requirements. Requirement 1a. What is the average cost of manufacturing a drink bottle in 2020? How does it compare to Wren's offer? The average cost of per bottle is than Wren's offer. 1. a. What is the average cost of manufacturing a drink bottle in 2020? How does it compare to Wren's offer? b. Can Grant use the answer in requirement 1a to determine the cost of manufacturing 255,000 drink bottles? Explain. 2. Grant's cost analyst uses annual data from past years to estimate the following regression equation with total manufacturing costs of the drink bottle as the dependent variable and drink bottles produced as the independent variable: y = $431,000+ $3.00x During the years used to estimate the regression equation, the production of drink bottles varied from 229,000 to 265,000. Using this equation, estimate how much it would cost Grant to manufacture 255,000 drink bottles. How much more or less costly is it to manufacture the bottles rather than to acquire them from Wren? 3. What other information would you need to be confident that the equation in requirement 2 accurately predicts the cost of manufacturing drink bottles
