Answer:
$40,000
Explanation:
Let p represent Stella's pay on s amount of sales. Her two pay options are ...
- p = 1200 + .02s
- p = 800 +.03s
Setting the two values of p equal, we have ...
1200 +.02s = 800 +.03s
400 = .01s . . . . . subtract 800+.02s
40,000 = s . . . . . multiply by 100
A sales amount of $40,000 would result in the same pay per month.
_____
You will note that this amount is the difference in base pay (400) divided by the difference in commission rate (0.01). Once you realize that, no equations are needed.
