One day a store sold 25 sweatshirts. White ones cost $11.95 and yellow ones cost $12.50. In all, $304.25 worth of sweatshirts were sold. How many of each color were sold?

Step-by-step explanation:

Let y represent the number of yellow sweatshirts sold. Then the total revenue is ...

  $11.95(25 -y) +$12.50(y) = $304.25

  $0.55y +$298.75 = $304.25 . . . simplify

  $0.55y = $5.50 . . . . . . subtract $298.75

  y = 10 . . . . . . . . . . divide by $0.55

  25-y = 15 . . . . the number of white sweatshirts sold

10 yellow and 15 white sweatshirts were sold.
