Question

For the past six months, Malika's utility bills (including electricity, heat, water, cable, and telephone) have been as follows: January: $99.85 February: $150.00 March: $85.25 April: $66.38 (due to a free month of cable television service) May: $180.96 June: $102.34 What is the average of her utility bills?

Answer 1

The average of anything means you add all the values and divide by the number of values. In this case you would add all the month's utility bills and divide by the number of bills included. However, in this instance, I would exclude April since this in an anomaly and she will not get a free month's cable every month. SO add the other other months together and divide by 5.
