5. Copyright 2014 © W. Seth Hunter ConsumerMath.org L2.1 Payments, Rents, and Utilities Wait!!! Weeks in a Month x Months in a Year 4 x 12 = 48 But there are 52 weeks in a year. What went wrong?

6. Copyright 2014 © W. Seth Hunter ConsumerMath.org L2.1 Payments, Rents, and Utilities There are NOT 4 weeks in a month! It is closer to 4 ½ weeks in each month. If you calculate your monthly bill based on 4 weeks in a month, you will be paying TOO MUCH! Wait!!!

8. Copyright 2014 © W. Seth Hunter ConsumerMath.org L2.1 Payments, Rents, and Utilities The Real Math Annual Rent = $4,800 Divide by 52 to get Correct Weekly Rent $4,800 ÷ 52 = 92.3076 round to $92.31

9. Copyright 2014 © W. Seth Hunter ConsumerMath.org L2.1 Payments, Rents, and Utilities The Real Math Correct Weekly Rent = $92.31 Incorrect Weekly Rent = $100.00 The Difference is $7.69 per week.

12. Copyright 2014 © W. Seth Hunter ConsumerMath.org L2.1 Payments, Rents, and Utilities Rent / Utilities Calculated per Room In this class you are responsible to find your own bills. You will use actual costs, but you don’t have to pay for a whole house worth of utilities. After all, you will probably only be renting one room. If your current home has 4 bedrooms, and your monthly utility cost is $400, then… $400 ÷ 4 rooms = $100 per Room
