“WE ARE WASHINGTON: PEOPLE OF THE FAIR”LESSON TWO
Math behind the Photo Salon
Objective
Calculate percentages to determine a prize-winning photo.
Lesson
When Eric Bastin of the Photo Salon has to choose a prize-winning photo, he uses percentages.
In this example he has 240 images entered in the division. He needs to have a target of 50 percent acceptance. The lowest
score is 13 and highest score is 24. To get approximately 50 percent, he needs to accept images that scored 20 and above.
That gives him an acceptance rate of 48 percent. Although it is difficult to match the exact percentage or image count he
needs, the table helps him make an educated decision of what scores to accept into the competition.
