The equation y-100x=2000 can be used to represent the monthly salary of a salesman, y, when he sells x computer systems. What is

Maru [420]

If "y" represents the monthly salary of a salesman then we can rearrange the equation so that "y" is in evidence:
y=2000+100x

If he sells no computers and "x" is the number of computer systems he sells, then x=0.
y=2000+100*0 <=> y=2000+0 <=> y=2000

If the salesman sells no computers, his monthly salary is of 2000.
