Question 99726: A small company produces both doll houses and doll furniture. The doll houses take 3 hours of labor to produce, and the furniture sets take 8 hours. The labor available is limited to 400 hours per week, and the total production capacity is 100 items per week. Existing orders require that at least 20 doll houses and 10 sets of doll furniture be produced per week. Write a system of inequalities representing this situation, where x is the number of doll houses and y is the number of furniture sets. Then graph the system of inequalitites.
I think I have found the system of inequalitites. I am not sure if they are correct though.
3x + 8y < 400; x + y < 100; x > or equal to 20; y > or equal to 10
I also came up with these points for the graph
(20,10); (66,24); (23,66); (64,26) Is this all correct?

Question 100073This question is from textbook Algebra 2: A Teaching Textbook
: I cannot seem to get a mathematical equation out of this problem:
The Jr. senator can work his way through a bureaucratic labyrinth in 50 minutes. The Sr. senator can work his way through a bureaucratic labyrinth in 30 minutes. Working together, how many minutes would it take them to work their way through 12 bureaucratic labyrinths?
I have worked and worked and am just stuck! 50x + 30y = 12 and substituting y = (12 - 50x)/30 just ends me up with 12 = 12 (which I already know!). Please help - words problems are my weak area here. Thank you!This question is from textbook Algebra 2: A Teaching Textbook

Question 100139: A club charters a plane at a cost of $15840 to take a group of members on a trip. At the last minute, 6 people in the group canceled, increasing the cost per person by $20. How many people originally intended to take this trip?
I set the original # of people = P
Cost/person = 15840/P
The people that went were = (P-6)
Final cost/person = 15840/(P-6)= 15840/P + 20
I did do a methodical 'guess and check' and did get what I think is the right answer (72), but how do I really work it out. On a test, that will be too time
consuming and in the real work, it is not practical.
Help! Also what would you classify this problem as?
Thanks
