Problem 2. Your hospital has been approached by a major HMO to perform all their MS-DRG 470 cases (major joint procedures). They have offered a flat price of $10,000 per case. You have reviewed your charges for MS-DRG 470 during the last year and found the following profile: Average Charge

$15,000

Average LOS

5 Days

Routine Charge

$3,600

Cost/Charge 0.80

Variable Cost % 60

In the above data set, assume that the hospital's cost to charge ratio is 0.80 for routine services and 0.75 for all other ancillary services. Using this information, what would the average cost of MS-DRG 470 be?

Asystem of linear equations with more equations than unknowns is sometimes called an overdetermined system. can such a system be consistent? illustrate your answer with a specific system of three equations in two unknowns. choose the correct answer below. a. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 6 b. no, overdetermined systems cannot be consistent because there are fewer free variables than equations. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 12 c. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 8 d. no, overdetermined systems cannot be consistent because there are no free variables. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 24
