As per the question, the pay check is $2100 per month,
The one bedroom apartment would rent $650 + 60( for the electricity bill) + 30( for gas + inteyrnet) + 20 for the parking space, that will be..
$650+$60+$20+$20+$10 = $770.
We have $2100 as our paycheck every month and the total amount for the apartment is $770.
So I think yes we can afford it.
