Answer:
Step-by-step explanation:
The options available to Joe are ($1800 + 6.5% of sales) and ($2100 + 4% of sales) for his salary. He chooses the option in which he would get higher salary. Sales are expected to lie between $5000 and $10000.
Let the sales be denoted by [tex]x[/tex] (in Dollars). Joe chooses first option if it is a higher number than the second.
⇒ if [tex]1800+\frac{6.5}{100}x>2100+\frac{4}{100}x[/tex]
[tex] \frac{2.5}{100}x>300\\x>12000[/tex]
So, he chooses first option if [tex]x(=Sales)>12000[/tex]. However sales is between $5000 and $10000. So, Joe will go with second option.
∴ Joe should choose $2100 + 4% of sales.
