Question: Tom needs to lower a rope down 6 stories. One story is 10 feet. The only rope being sold is 20 feet long but you lose 25% when lashing them together. How many pieces of rope will he need to buy?
Answer with step-by-step thinking: He needs 10 * 6 = 60 feet. He loses 20 * .25 = 5 feet each time. So he gets 20 - 5 = 15 feet from each piece. That means he needs 60 / 15 = 4 pieces of rope.
So the answer is 4.

Question: Ravi has some coins. He has 2 more quarters than nickels and 4 more dimes than quarters. If he has 6 nickels, how much money does he have?
Answer with step-by-step thinking: Ravi has 6 + 2 = 8 quarters. He has also 8 + 4 = 12 dimes. A nickel is worth 5 cents so Ravi's nickels amount to 6 x 5 = 30 cents. A quarter is worth 25 cents so his quarters amount to 8 x 25 = 200 cents. A dime is worth 10 cents so his dimes amount to 12 x 10 = 120 cents. therefore, Ravi has 30 + 200 + 120 = 350 cents.
So the answer is 350.

Question: Hooper Bay has twice as many pounds of lobster than the two other harbors combined. If the other two harbors have 80 pounds of lobster each, how many pounds of lobster are the three harbors holding?
Answer with step-by-step thinking:
Since the other two harbors have 80 pounds of lobsters each, they have a total of 80 + 80 = 160 pounds of lobster. Since Hooper Bay has two times more lobsters than the other two harbors combined, it has 2 * 160 = 320 pounds of lobster. In total, the three harbors have 320 + 160 = 480 pounds of lobster.
So the answer is 480.
