Kenton watched 2000 adult men and women board a cruise ship. Half of the adults were women. If 20$\%$ of the women and 9$\%$ of the men were wearing sunglasses, what was the total number of men and women wearing sunglasses?
First, we know that there are 2000 adults on the cruise ship. Half of them are women, so there are 1000 women. That means there are 1000 men. That's true. We know that half of the adults were women, which means that there were 2000/2 = 1000 women. Of those 1000 women, 20% were wearing sunglasses, so 1000 * 20% = 1000 * 0.2 = 200 women had sunglasses. Now we need to do the same thing for the men. We know that half of the adults were men, which means that there were 2000/2 = 1000 men. Of those 1000 men, 9% were wearing sunglasses, so 1000 * 9% = 1000 * 0.09 = 90 men had sunglasses. So in total, 200 + 90 = 290 adults had sunglasses.
