The sum of black and white shirts is 63 + 42 = 105. The number of jeans in the store is (2 / 3) x 105 = 70. The sum of ties and belts is 34 + 40 = 74. The number of scarfs in the store is 74 / 2 = 37. There are 70 - 37 = 33 more jeans than scarfs in the store.
This justifies what answer for what question? Q & A:
A clothing store has an inventory of 34 ties, 40 belts, 63 black shirts, and 42 white shirts. The number of jeans in the store is two-thirds of the sum of black and white shirts, and the number of scarves is half the number of the sum of ties and belts. How many more jeans are there than scarves?
33
