| Question 504623:  Hi I know how to solve systems of equations, but I'm having trouble setting this one up. It is a word problem.
 AMC Homes, Inc is planning to build three and four bedroom homes. Consumer demand indicates a need for three times as many four-bedroom homes as for three-bedroom homes. The net profit from each three-bedroom is $16,000 and $17,000 for each four bedroom. If the total net profit is $13.4 million how many homes of each type should they build?
 Thanks for any help you might have :)

You can put this solution on YOUR website! AMC Homes, Inc is planning to build three and four bedroom homes. -----
 Consumer demand indicates a need for three times as many four-bedroom homes as for three-bedroom homes.
 Let "f" be # of four-bedroom homes
 Let "t" be # of three-bedroom homes.
 ------
 f = 3t
 ----
 The net profit from each three-bedroom is $16,000 and $17,000 for each four bedroom. If the total net profit is $13.4 million
 16000t + 17000f = 13,400,000
 -----
 Substitute for "f" and solve for "t":
 16000t + 17000(3t) = 13,400,000
 ---
 Divide thru by 1000 to get:
 16t + 17(35) = 13.499
 --
 16t + 51t = 13,400
 67t = 13,400
 t = 200 (# of three-bedroom houses to build)
 ---
 Solve for "f":
 f = 35
 f = 3*200 = 600 (# of four-bedroom houses to build)
