Calculating Costs for Room Molding

The video tutorial covers two application problems related to cost calculations. The first problem involves calculating the cost of carpeting a rectangular room by determining its area and multiplying it by the cost per square foot. The second problem involves calculating the cost of floor molding by determining the room's perimeter and multiplying it by the cost per foot. The tutorial provides step-by-step instructions for solving these problems, including multiplication techniques and handling decimal points in cost calculations.
