Jim ross is an automobile salesman who receives a salary of $500 per week plus a commission of 3% on all sales. during a four-week period he sold $42,000 worth of cars. what were jim's average earnings?

4 * 500 = $2,000 

Then, you must calculate how much he earned by the commission: 

$42,000 * 3% 

(3% = 3/100) 

42,000 * 3/100 = 420 * 3 = $1260 

Finally, you add what he earned form the commission plus the 4 weeks salary: 

$2,000 + $1260 = $3,260

Ithink the answer is: it is likely.

The answer is b: step 2.
