Leviafan [203]

$3753.79

Step-by-step explanation:

Fixed Expenses = $2085.44 x 0.30

Fixed Expenses = $625.63

Now you need to take your Fixed Expenses and multiply that to the number of months you want to save for.

$625.63 x 6 = $3753.79

So you will need to save $3753.79 for 6 months worth of an emergency fund.
