You haven't provided the $ or % that he gets, but I will attempt to use algebraic terms to explain it instead.
If the salesman sells a car for $<em>a</em> and gets <em>b</em>% of the sale price as commission, then what you need to do is divide the <em>a</em> by 100, then multiply it by <em>b</em> to find out <em>b</em>% of <em>a</em>. This will be the commission that he will earn.
<em>a </em>/ 100 x <em>b</em> = commission earned in $
Edit
<em>You've now supplied me with the $ and %, let me explain it again.</em>
To find out the commission that he will earn, you divide 8,100 by 100 then multiply it by 9.
8,100 / 100 = 81
81 x 9 = $729 commission earned.
Answer:
180 ways
Step-by-step explanation:
Aerospace companies (A) = 5
Energy development companies (D) = 3
Electronics companies (E) = 4
Number of aerospace stocks bought (a) = 2
Number of Energy development stocks bought (d) = 2
Number of Electronics stocks bought (e) = 2
The number of ways that the investor can select his six investments from the recommended list is given by the combination of picking two out five aerospace companies, multiplied by picking two out three energy development companies, multiplied by picking two out four electronics companies:
There are 180 ways for the investor to select the six companies.
