Paula Boothe, president of the Swifty Corporation, has mandated a minimum $8\%$ return on investment for any project undertaken by the company. Given the company$$s decentralization, Paula leaves all investment decisions to the divisional managers as long as they anticipate a minimum rate of return of at least $10\%.$ The Energy Drinks division, under the direction of manager Martin Koch, has achieved a $15\%$ return on investment for the past three years. This year is not expected to be different from the past three. Koch has just received a proposal to invest $ $2,000,000$ in a new line of energy drinks that is expected to generate $ $240,000$ in operating income.
