We present a fuzzy optimization problem in business and economics. In this problem., a fuzzy price is determined by using a linear two degree demand functions. The objective is to find the optimal fuzzy revenue, which is derived from the fuzzy price. We use level (lambda, 1) interval-valued fuzzy numbers to consider the fuzzy price and the fuzzy revenue. Using signed distance to defuzzify, we can obtain the demand function and revenue function in the fuzzy sense. What follows is that we can find the maximum revenue in the fuzzy sense.
