Calculating Total Cost of Bills

The video tutorial explains how to calculate the cost of a bill based on meter readings. It starts by identifying the new and old readings, calculates the units used, and then determines the total cost by multiplying the units by the cost per unit. The final cost is presented in both pence and pounds.
