1. Suppose that a hospital charges you $220 per day if you sty in a private room and $166 / day if you stay in a room for 4 people. Assume that the amount you pay is the sum of a constant amount (for the services you receive) and an amount which varies inversely with the number of people the room will hold (to pay for your share of the room)
- a] Calculate the constant amount you pay for services and the proportionality constant in the variation function.
- b] What does the hospital charge for a room, exclusive of the services to the paitent?
- c] How much would you expect to pay / day if you stayed in
i. semi-private room holding 2 people?
ii. a ward holding 20 people?
2. I'm not sure what you put here for relevant equations? But this section deals with functions of more than one independent variable where in y=kx there is more than 1 x. Something like that.
- a] total amount = k1 + amount x
amount x = k2 / number of people
then i plugged in for amount x and got --> total amount = k1 + k2/ number of people
so now a] is asking for the value of the two ks? But which numbers do i plug in? and can I combine k1 + k2 to make a k3?
- b] I think for this you use the equation - total amount = k2/ number of people but w/o solving a, i can't solve b
- c] this is plugging and chugging.. if I knew the equation from a]
Any help is appreciated.
Thanks so much in advance!
