Lizzy: 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 = $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. Final answer: 872.
