Step-by-step reasoning process: For each type of shirt, he needed to buy, 40 employees / 4 = 10 shirts. White men's T - shirts cost $20 / shirt * 10 shirts = $200. White women's T - shirts cost $5 less, or ($20 / shirt - $5 / shirt) * 10 shirts = $15 / shirt * 10 shirts = $150. Black men's t - shirts cost, $18 / shirt * 10 shirts = $180. Black women's T - shirts cost $ 5 less, so ($18 / shirt - $5 / shirt) * 10 shirts = $13 / shirt * 10 shirts = $130. Now add up all these quantities to find the total: $200 + $150 + $180 + $130 = $660.
