Answer:
=((SUM(PUT RANGE OF MOTHLY EXPENSES HERE)*12)+SUM(PUT RANGE OF YEARLY EXPENSES HERE))/12
Step-by-step explanation:
Adds all of the Monthly Expenses : SUM(PUT RANGE OF MOTHLY EXPENSES HERE)
Multiplies the result by 12: *12
Then adds all of the Yearly Expenses to the product of Steps 1 and 2 : SUM(PUT RANGE OF YEARLY EXPENSES HERE)
Divides this new sum by 12: /12
=((SUM(PUT RANGE OF MOTHLY EXPENSES HERE)*12)+SUM(PUT RANGE OF YEARLY EXPENSES HERE)/12)
