Question

A Salesman priced a four wheeler at $3,500 the first day it was on the market it's likely that he reduced the price by 10% what was the new price

Answer 1

The new price would be 10% less than full price.  In other words, the new price would be 90% of full price.

Thus, 0.90($3500) = $3150.  This is the new price.
