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?
This month, Vince earns 80 x $18 = $<<80*18=1440>>1440.
The amount he allocates for recreation and relaxation is 20/100 x $1440 = $<<20/100*1440=288>>288.
Thus, his monthly expenses is $280 + $288 =$<<280+288=568>>568.
Therefore, he saves $1440 - $568 = $<<1440-568=872>>872.
