You can put this solution on YOUR website! a machine company has an incentive plan for its salesperson.For each machine that a salesperson sell,the commission is $40.The commission for every machine sold will increase by $0.04 for each machine sold over 600.For example the commission on each 602 machine sold is $40.08. How many machines must salesperson sell in order to earn $30,800 ?
-------------
EQUATION:
Commission = 40x + 0.04(x-600) where x is number of machines sold and
the domain is x >= 600
-----------------------------
Find "x" if Commision is 30,800
30800 = 40x + 0.04(x-600)
40x + 0.04x - 24 = 30800
40.04x = 30824
x = 768.83
Rounding up the salesperson must sell 769 machines.
