Human: Vince owns a hair salon and he earns $18 per head. His monthly expenses are $280 for rent and electricity and 20% of his earnings are allocated for recreation and relaxation. He will save the rest. How much does he save if he serves 80 customers a month? Assistant:
This month, Vince earns 80 x $18 = $1440.
The amount he allocates for recreation and relaxation is 20/100 x $1440 = $288.
Thus, his monthly expenses is $280 + $288 =$568.
Therefore, he saves $1440 - $568 = $872.
