Answer:
$3753.79
Step-by-step explanation:
To find your emergency fund, you need to get your fixed expenses as the base.
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.
