Question 82743: Could you help me solve the rest ofthis and check to see if what I did do was right. It is not from a textbook. Thank you

3) It is approximately 300 miles from Chicago, Illinois, to St. Louis, Missouri. Allowing for various traffic conditions, a driver can average approximately 60 miles per hour.
a) How far have you traveled after 3 hours?
Answer: 180 miles
Show work in this space: D = RT
60(3) = 180
b) How far have you traveled after 4 hours?
Answer: 280 miles
Show work in this space: D = RT 60(4) = 280
c) How far have you traveled after t hours? i.e. write a linear function that expresses the distance traveled, d, as a function of time, t.
Answer:

d) How far will you HAVE LEFT to travel to reach St. Louis after you have traveled 3 hours?
Answer: 120 miles
Show work in this space: 300 – 180 = 120
e) How far will you HAVE LEFT to travel to reach St. Louis after you have traveled 4 hours?
Answer: 20 miles
Show work in this space: 300 – 280 = 20

f) How far will you HAVE LEFT to travel to reach St. Louis after you have traveled t hours? i.e. write a linear function that expresses the distance to be traveled to reach St. Louis, s, as a function of time, t.

Question 82741: Could you please help me solve this question. I did some of it. Thank you
It is not from a textbook, sorry.
2) In most businesses, increasing prices of their product can have a negative effect on the number of customers of the business. A bus company in a small town has an average number of riders of 1,000 per day. The bus company charges $2.00 for a ride. They conducted a survey of their customers and found that they will lose approximately 50 customers per day for each $.25 increase in fare.
a) Given the description above, graph the function, identify the graph of the function (line, parabola, hyperbola, or exponential), find the slope of the graph, find the price at which there will be no more riders, and find the maximum number of riders possible. The vertical axis is the number of riders per day, and the horizontal axis is the fare.
Graph:
Graph Type:
What is the slope of the graph?

b) The bus company has determined that even if they set the price very low, there is a maximum number of riders permitted each day. If the price is $0 (free), how many riders are permitted each day?
Answer:
c) If the bus company sets the price too high, no one will be willing to ride the bus. Beginning at what ticket price will no one be willing to ride the bus?
Answer: $7.00 per ticket

Question 82799: A small company produces both standard and deluxe playhouses. The standard playhouses take 12 hrs of labor to produce, and the deluxe playhouses take 20 hrs. The labor available is limited to 800 hrs per week, and the total production capacity is 50 items per week. Existing orders require the company to produce at least 10 standard playhouses and 15 deluxe playhouses per week.
Write a system of inequalities representing the situation, where x is the number of standard playhouses and y is the number of deluxe playhouses.
Then graph the system of inequalities.
