Q: At a shop in Japan, women's T-shirts are sold every 30 minutes for $18, and men's T-shirts are sold every 40 minutes for $15. This shop is open from 10 am until 10 pm. How much does the shop earn selling T-shirts per week?
A:
First, the shop is open 12 hours * 60 minutes = 720 minutes per day. So, 720 / 30 = 24 women's T - shirts sold per day. The shop earns 24 * $18 = $432 selling women's T - shirts per day. Similarly, 720 / 40 = 18 men's T - shirts are sold per day. The shop earns 18 * $15 = $270 selling men's T - shirts per day. The shop earns $432 + $270 = $702 per day selling T - shirts. The shop earns $702 * 7 = $4914 per week. The answer is 4914.
