Question 1208482
<pre>
2 Using Desmos : 
Luke is starting a landscaping business and will cut lawns. His startup cost to purchase two lawn mowers is $450. He will use $1 in gas for each lawn and will charge $10 per lawn.

a) Write a linear system to represent this problem. Remember to define your variables 

With number of lawns to be mowed being x, we get revenue EQUATION as: R(x) = 10x 
                                                    Cost EQUATION as: C(x) = x + 450
These are the required equations for your system.

As you may know, Profit = Revenue - Cost. So, in this case, Profit = R(x) - C(x)
                                                            Profit = 10x - (x + 450) = 10x - x - 450 = 9x - 450

And, BREAK-EVEN units occur when R(x) = C(x), or in this case, 10x = x + 450</pre>
