Question

To determine how much you should budget for food each month, take the average of the expense over the last several months. If over the last four months you spent $120, $137, $82, and $57 on groceries, how much should you budget for food this month?

Answer 1

To find the average add all the amounts together then divide by the number of amounts:

120 + 137 + 82 + 57 = 396

Average = 396 / 4 = 99

Budget = $99
