Question 983057: Pls help solve below two questions:
Question No. 1
x/3 - y/4 = 2x - y +12
Question No. 2
A Company manufactures two different products, A and B. Each unit of product A costs $6 to produce and each unit of product B costs $4. The Company insists that total costs for the two products be $500.
(a) Define the cost equation which states that the total cost of producing x units of product A and y units of product B equals $500
(b) Assuming the Company has agreed to fill an order for 50 units of product A, how many units of product B should be produced if total costs are to be kept at $500?

Question 983679: Determine the slope and the y-intercept. Then draw a graph.
g(x)= -0.25x
slope:-0.25
y-intercept: (0,0)
I plotted (0,0) on the graph. For the slope and rise and run plot, I have (1, -0.25). The book's rise and run plot is (4,-1). Please help as I'm confuse with the rise and run of -0.25.

Question 984073: 4. The number of dollars per month it costs you to own a car is a related to the number of
kilometers per month that you drive. Based on information in an issue of Time magazine, the cost
varies linearly with relation to the distance driven. It is known to cost $365 per month if 300 km
are driven, and $515 per month 1500 km are driven. (3 points each)
