Dinora sells pupusas (a Salvadoran snack food) for $1 each. She spends $80 on ingredients and two hours to make 350 pupusas. On a typical day, she sells 300 pupusas and gives away the rest to her family and friends. A long-standing customer gives Dinora the opportunity to supply 350 pupusas to a party at $0.90 each. Dinora has to spend $25 to transport the pupusas to the customer's house. Dinora cannot both accept this opportunity and sell the pupusas at her usual location.
