Your housing and fixed expenses are $702.38/month. what is your realized income for the month if your expenses account 30%

We are asked to solve for the monthly income given that 30% of it goes to your expenses.
Expenses per month = $702.38
Expenses percent from income = 30% = 0.3
Total income per month  = X

The solution is shown below:
$702.38 = 30% * X
X = $702.38 / 0.3
X = $2,341.27

The total income is $2,341.27.
