Question: Six more than twice as many ducks go to North Pond as go to Lake Michigan. If Lake Michigan has 100 ducks, how many ducks can you safely estimate there will be at North Pond?
Answer: To determine the number of ducks at North Pond, we must first perform 100 * 2 = 200 to find the number to add 6 ducks to. We then take this number and add 6 to it, performing 200 + 6 = 206 ducks in total at North Pond. The answer is 206.

Question: A party hall has 3 decorative light bulbs; a red light bulb which comes on every 2 seconds, a green one every 3 seconds and a blue one every 4 seconds. If they are put on at the same time, what is the shortest time after which the three bulbs will be on at the same time?
Answer: The blue light bulb comes on every 2 seconds so it will be on after 2, 4, 6, 8, 10, 12, 14... seconds (multiples of 2). The red light bulb comes on every 3 seconds so it will be on after 3, 6, 9, 12, 15, 18... seconds (multiples of 3). The blue light bulb comes on every 4 seconds so it will be on after 4, 8, 12, 16, 20... seconds (multiples of 4). The shortest time after which all three will be on is 12 seconds which is the least common multiple of the set of multiples. The answer is 12.

Question: Joanie wants to join a gym to get into shape. The gym costs $12 per month and has a $50 down payment. How much will she need to pay for the first 3 years?
Answer: The membership costs $12 * 12 months = $144 per year. For three years, the monthly membership fee will be $144 * 3 = $432. The total amount paid for 3 years will be $432 + $50 = $482. The answer is 482.

Question: A blacksmith has 400kg of iron to make horseshoes for neighbouring farms and stables. There are 2 farms nearby, each of which has 2 horses. There are 2 stables nearby which all have 5 horses each. While the blacksmith is crafting, a riding school reaches out and asks for as many horseshoes as possible for their own horses. The blacksmith promises to give them however many horseshoes he has left when he has finished his orders for the farms and stables. If each horseshoe needs 2kg of iron, how many horses will get new horseshoes at the riding school?
Answer:
The blacksmith can create a total of 400kg iron / 2kg iron per horseshoe = 200 horseshoes. The farms need enough horseshoes for 2 farms * 2 horses each = 4 horses. The stables need enough horseshoes for 5 stables * 2 horses each = 10 horses. So in total, the farms and stables have 4 + 10 = 14 horses that need horseshoes. This is a total of 14 horses * 4 horseshoes per horse = 56 horseshoes. This means the blacksmith has 200 total horseshoes 56 horseshoes for the stables and farms = 144 horseshoes left for the riding school. The riding school therefore will have enough horseshoes for 144 horseshoes / 4 horseshoes per horse = 36 horses. The answer is 36.
