The yellow T-shirt costs three times as much as the blue T-shirt.
To solve this problem
We can divide the price of the yellow T-shirt by the price of the blue T-shirt.
Ratio = (Price of Yellow Shirt) / (Price of Blue Shirt)
Ratio = $24 / $8
Ratio = 3
So, the yellow T-shirt costs three times as much as the blue T-shirt.
This can also be represented by the following equation:
Yellow Shirt Price = 3 * Blue Shirt Price
$24 = 3 * $8
The ratio and the bar diagram both show that the price of the yellow T-shirt is three times higher than that of the blue T-shirt.
