Question 613734: I'm stumped, I've worked on this probably simple problem for two hours and just can't get it, my book doesn't even explain anything like it.

Here it is:
You plan to start taking an aerobics class. Nonmembers pay 5$ power class. Members pay a6$ monthly fee plus an additional 4$ pet class. Three monthly cost, y, of taking x classes can be modeled by the following linear system
Y=5x
Y=4x+6
Using graphing to solve the system.

The solution set is { }
Type an ordered pair. Use integers or decimals for any numbers in the expression.
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
Graph y = 5x (shown in green) and y = 4x+6 (shown in blue) to get

Notice how they cross at the point (6,30). If it's hard to see this, use the "intersect" or "trace" feature on your graphing calculator.

So the solutions are x = 6 and y = 30

Answer: The solution set is { (6,30) }
