Question: A zoo has 16 pandas, paired into mates (in the same zoo). Only 25% of the panda couples get pregnant after mating. If they each have one baby, how many panda babies are born?
Answer: First divide the number of pandas by 2 to find the number of couples: 16 pandas / 2 = 8 panda couples. Then multiply that number by 25% to find the number of babies: 8 panda couples * 25% = 2 panda babies. The answer is 2.
[Question]Cecil has $600. Catherine has $250 less than twice as much as Cecil while Carmela has $50 more than twice Cecil's money. How much money do they have altogether?
[Answer]Twice as much as Cecil's money is $600 x 2 = $1200. So, Catherine has $1200 - $250 = $950. While Carmela has $1200 + $50 = $1250. Hence, they have a total of $600 + $950 + $1250 = $2800. The answer is 2800.

Question: Eve wants to buy her 3 nieces cooking gear that's made for kids. The hand mitts cost $14.00 and the apron is $16.00. A set of 3 cooking utensils is $10.00 and a small knife is twice the amount of the utensils. The store is offering a 25% off sale on all cooking gear. How much will Eve spend on the gifts?
Answer: A small knife is twice the amount of the utensils that costs $10.00 so the knife costs 2 * 10 = $20.00. All total, each little kit will costs $14.00 for mitts, $16.00 for an apron, $10.00 for utensils and $20.00 for a knife for a total of 14 + 16 + 10 + 20 = $60.00. Each kit costs $60.00 and they are currently 25% off so that's a savings of 60 * .25 = $15.00. The kits are $60.00 and they are $15.00 off so they now cost 60 - 15 = $45.00. She needs to buy 3 kits and each kit costs $45.00 so that's 3 * 45 = $135.00. The answer is 135.
[Question]Josh built his little brother a rectangular sandbox. The perimeter of the sandbox is 30 feet and the length is twice the width. What is the width of the sandbox?
[Answer]There are four sides to a rectangle, the width is W and so the length is 2W, and we can put that in this equation: W + W + 2W + 2W = 30 feet. If we add the sides together, we get 6W = 30 feet. To find W, we divide both sides by 6, like this: 6W / 6 = 30 feet / 6, so W = 5 feet. The answer is 5.
[Question]Dream's car consumes 4 gallons of gas per mile. If she drives 400 miles today and 200 more miles tomorrow than today, how many gallons of gas will the car consume?
[Answer]
If she drives 400 miles today, the car will have consumed 4 * 400 = 1600 gallons of gas. Tomorrow, if she drives 200 more miles, the total distance will be 200 + 400 = 600 miles. The fuel consumption by the car tomorrow is 4 * 600 = 2400 gallons. The car's total fuel consumption in the two days is 2400 + 1600 = 4000 gallons. The answer is 4000.
