My question is: Juan bought T-shirts for his employees. He bought shirts for men and women. Women's t-shirts are $5 cheaper than men's t-shirts of the same color. His company has 2 sectors, one in white t-shirts and the other in black t-shirts. He paid $20 for white men's t-shirts and $18 for black men's t-shirts. The 2 sectors have the same number of men and women, with a total of 40 employees. How much did he spend total on buying t-shirts? Your thoughts:
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. The final answer: 660.
