Given :
A store pays $1.25 per pound for cat litter.
One cubic foot of cat litter weighs about 48 pounds.
To Find :
the selling price of cat litter in the container shown when the markup is 20%.
( dimensions are 6 in x 7 in x 9 in )
Solution :
Volume of container,
V = 6 in x 7 in x 9 in
V = 378 in³
We know, 1 cubic foot = 1728 in³.
So, weight of litter in 378 in³ is :

Selling price with 20% markup is :
![P = [1.25+(1.25* 0.20)] * 10.5\\\\P = \$15.75](https://img.qammunity.org/2022/formulas/mathematics/high-school/k98irizr51oihcqy6poxkcgi8ax46kvf53.png)
Therefore, the price of litter in 1 container of given dimensions is $15.75 .
