An average can be calculated by the quotient of the sum of all terms and the number of terms. In this instance, there are 4 pairs of shoes with three given values. Let's say x is the price of the fourth pair of shoes.

$\frac{35+40+55+x}{4} =50$

Clear the fraction by multiplying both sides of the equation by 4.
