First let's add all of his expenses together:
$420 + $168 + $210 + $42 + $70 + $224 + $70 + $70 + $56 + $70 = $1,400
Immediately we are able to see that all of his expenses use up the entire $1,400 in his budget. With $224 going towards entertainment there is no way Mike can expect to save for an apartment or car as he is choosing to spend any potential investable income on entertainment.
