Sabrina is contemplating a job switch. She is thinking of leaving her job paying $85,000 per year to accept a sales job paying $45,000 per year plus 15 percent commission for each sale made. If each of her sales is for $2,000, what is the least number of sales she must make per year if she is not to lose money because of the job change?
Pick.
A) 57  B) 133  C) 178  D) 377  E) 378
Lets say she sales x items so her commission will be : x * 2000*15/100 = 300x   Salary difference is:   85000 - 45000= 
<gadget id="calculator">  85000 - 45000</gadget>
<output>40_000</output>
40000   So commission must at least be equal to salary difference i.e. x= 40000/300= 133 (Approx).   Hence answer is 133
