Question: The big bottles of mango juice hold 30 ounces and cost 2700 pesetas each. The small bottles hold 6 ounces and cost 600 pesetas each. How many pesetas would be saved by buying a big bottle instead of smaller bottles for the same volume of juice?
Answer: Step-by-step reasoning process: The equivalent is 30 / 6 = 5 small bottles. Five small bottles at 600 pesetas each is 5 * 600 = 3000 pesetas. The savings is 3000 - 2700 = 300.
So the answer is 300.

Question: Tom is cutting a piece of wood to make a shelf. He cut the wood to 143 cm, but it is too long to fit in the bookshelf he is making. He decides to cut 25 cm off the board. But it turned out longer than the other boards. He had to cut off 7 cm from each to make them the same size. How long were the boards before he cut the 7 cm off?
Answer: Step-by-step reasoning process: After the first cut, the board was 143 - 25 = 118 cm. The other boards were 118 + 7 = 125 cm before they got cut.
So the answer is 125.

Question: May can knit 3 scarves using one yarn. She bought 2 red yarns, 6 blue yarns, and 4 yellow yarns. How many scarves will she be able to make in total?
Answer:
Step-by-step reasoning process: May will be able to make 2 x 3 = 6 red scarves. She will be able to make 3 x 6 = 18 blue scarves. And she will be able to make 4 x 3 = 12 yellow scarves. Therefore the total scarves she can make is 12 + 18 + 6 = 36.
So the answer is 36.
