Step-by-step explanation:
To find the average monthly electric bill cost for the Cox family, you need to add up the costs for each month and then divide the sum by the number of months.
Here are the steps:
1. Add up the costs for each month:
- September: $87.55
- October: $97.34
- November: $100.44
- December: $156.88
The sum of these costs is $87.55 + $97.34 + $100.44 + $156.88 = $442.21.
2. Determine the number of months. In this case, there are 4 months.
3. Divide the total cost by the number of months to find the average:
Average monthly electric bill cost = $442.21 ÷ 4 = $110.55.
Therefore, the Cox family's average monthly electric bill cost is $110.55.
