A Sofa stores markup rate is 1/3 of the wholesales price. What is the wholesale price of a sofa if the markup is $90?

Th wholesale would be $30

What you need to do is 90 * 2 = 270

to make 1/3 a whole number you need to add 2 to the one and then take the 2 and multiply it by the 2 the to is so the go 1 + 2 = 3 or 3/3
