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?

Answer 1

• white: 15
• yellow: 10

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.
