Reasoning and answer: There were 20 + 5 = 25 basketballs. There were 2 x 20 = 40 tennis balls. And, there were 20 + 10 = 30 baseballs. So, there were 20 + 25 + 40 + 30 = 115 soccer balls, basketballs, tennis balls and baseball altogether. Therefore, Reynald bought 145 - 115 = 30 volleyballs,.
The answer: 30

In total she will need 10 shirts between Tuesday and Saturday and 1 shirt for Monday and Sunday = 11 shirts.
The answer: 11

Reasoning and answer: On the tall hills, he sleds down 2 tall hills * 4 times per tall hill = 8 times. He sleds down the small hills half as often so he sleds down each hill 4 times per tall hill / 2 = 2 times per small hill. On the small hills, he sleds down 3 small hills * 2 times per small hill = 6 times. So in total, Wilson sled down the hills 8 times on tall hills + 6 times on small hills = 14 times.
The answer: 14
