Each year, Miller Motors surveys 7,700 former and prospective customers regarding satisfaction and brand awareness. For the current year, the company is considering outsourcing the survey to RBG Associates, which has offered to conduct the survey and summarize results for $34,412. Richard Miller, the president of Miller Motors, believes that RBG will do a higher-quality job than his company has been doing but is unwilling to spend more than $10,000 above current costs. The head of bookkeeping for Miller has prepared the following summary of costs related to the survey in the prior year: $17,800 5,400 Mailing Printing (done by Lester Print Shop) Salary of Pat Fisher, part-time employee who stuffed envelopes and summarized data when surveys were returned (143 hours x $14) Share of depreciation of computer and software used to track survey responses and summarize results Share of electricity/phone/etc. based on square feet of space occupied by Pat Fisher vs. entire company Total 2,002 1,280 650 $27,132 What is the incremental cost or savings of going outside vs. conducting the survey as in the past?

A ray of light originating in a vacuum is incident upon a body of water (n = 1.33). What can you say about the refracted angle if the incident angle is between 0° and 90°? A, B, and C are all possible, depending on the specific value of the incident angle. Two of A, B, and C are possible, depending on the specific value of the incident angle. The refracted angle is less than the incident angle. The refracted angle is equal to the incident angle. The refracted angle is greater.

Find the order and degree of the differential equation: (d^(3)y)/(dx^(3))+sqrt{4}((d^(4)y)/(dx^(4)))=2xy(dy)/(dx). Form a differential equation by eliminating the arbitrary constant a and b from the equation y=ax^(2)-6bx. Find the general solution of the differential equation by using variable separable method: (dy)/(dx)=(xy+4x-y-4)/(xy-2x+4y-8). Solve by using Homogeneous differential equation method: 4(dy)/(dx)=(4y)/(x)+tan((y)/(x)) Find the general solution of the non-homogeneous differential equation: (dy)/(dx)=(x+y+4)/(2x+2y+6).
