A salesperson at a furniture store earns a 3% commission on all sales. How much commission does the salesperson earn on a $1400 sale?

A.$21


B) $42


C) $420


D) $1,420

Respuesta :

Okay since you have the first answer already i'll give you the second.

So to find out a percentage you have to make a proportion.

So what you would do is 

Divide 3 into 100 and multiply that by 1400 which is the sale.

3÷100×1400=42 

Answer 42

Hope this helps :)
