A motorcycle shop maintains an inventory of three times as many new bikes as used bikes. If there are 105 new bikes how many used bikes are now in stock?

If the motorcycle shop has three times as many new bikes as used bikes, and there are 105 new bikes, we can set up the equation: 3x = 105, where x represents the number of used bikes. Solving for x gives us x = 105 / 3, which equals 35. Therefore, there are 35 used bikes in stock.
