Answer:
$ 312.17
Step-by-step explanation:
We have to want to save an emergency fund based on household expenses, the first thing is to calculate how much to save those 4 months would be:
702.38 * 4 = 2809.52
In other words, you will need $ 2809.52 to save for 4 months
Now we must divide by 9 because that is the number of months it will take to save, therefore:
2809.52 / 9 = 312.17
That is to say, $ 312.17 per month, for 9 months to save 4 months of expenses.
