USE MATLAB TO SOLVE THIS PROBLEM

In electrical utilities, customers are charged the total number of KWhr (kilo-watt hours) used in a one month period. The equation used is KWhr = Wt/1000 where W = the watts of energy used by an appliance and t is the amount of time (in hours) the appliance was in operation. The constant 1000 converts the result from Watt-hours to Kilowatt-hours. The table below gives data describing the wattage used by a given appliance (A1 through A5) and the amount of time the appliance was in operation for that month.

1. Calculate the KWhr used by each individual appliance.
2. The total KWhr used by all appliances.
