Ответ:
Let the commission is represented by c and sales is representes by s.
Since there is a direct relationship between them, so the equation is
Where k is the constant of proportionality .
Now we substitute the given values of c and s and solve for k, that is
Dividing both sides by 100
Now we again use the same formula with s=150 and solve for c, that is
Correct option is B .
