Answer:
$5004.50
Step-by-step explanation:
The most straightforward computation is as follows:
on the first $50,000: 0.02×50,000 = 1,000
on the next $100,000: .025×100,000 = 2,500
on the next 200,150 -150,000 = 50,150: 0.03×50,150 = 1504.50
So, the total commission is ...
$1000 +2500 +1504.50 = $5004.50
McKenzie gets a commission of $5,004.50 on $200,150 worth of sales.
_____
Alternate method
The commission function can also be described as ...
2% for sales of $50,000 or less
2.5% less $250 for sales of $150,000 or less
3% less $1000 for sales of $150,000 or more
Using this formulation, the commission on $200,150 is ...
0.03×$200,150 -1,000 = $6004.50 -1000 = $5004.50 . . . . same as above
