Question

julie has a choice between receiving a monthly salary of $1800 from furniture by Design or a base salary of $1600 and a 4% commission on the amount of furniture she sells during the month. For what amount of sales will the two choices be equal.

Answer 1

I solved this one based on how I would figure it out for my staff in the retail industry.

 

We need to figure out how much Julie needs to sell to earn $200 per month.  That would make the salary of $1800 equal the salary plus commission.

 

$200 is 4 percent of what she sells.

 

I made it into a simple formula:

 

4/100 (4 percent is 4 over 100) = 200/x

 

4x = 20,000

x = 5,000

 

This can be double-checked by multiplying 5000 by .04 (4 percent is also .04).  The answer is $200.
