Question: Carl is hosting an open house for his new business. He knows 50 people will show up and hopes that another 40 people will randomly show up. He’s created 10 extravagant gift bags for the first 10 people who visit his shop. He’s made average gift bags for 20 people but needs to make enough for everyone who visits to have one. How many more bags does he need to make?
Answer: He knows 50 people are showing up and he’s hoping 40 more people will drop in for a total of 50 + 40 = 90 people. He’s made 10 extravagant gift bags and 20 average bags for a total of 10 + 20 = 30 bags. He hopes 90 people will show up and has already made 30 bags so he needs to make 90 - 30 = 60 more gift bags. The answer is 60.
[Question]Zoe made a total of $8,000 cleaning pools and babysitting. She babysat Julie three times as often as she babysat Zachary. The number of times she babysat Zachary was 1/5 the number of times she babysat Chloe. If Zoe made $600 babysitting Zachary, how much did she earn from pool cleaning?
[Answer]From babysitting Julie, Zoe made 3 * 600 = 1800 dollars, since she made $600 babysitting Zachary and she babysat Julie three times as often. Since she babysat Zachary 1 / 5 as often as she babysat Chloe, she made an additional 5 * 600 = 3000 dollars from babysitting Chloe. All together, the babysitting sessions made Zoe 600 + 1800 + 3000 = 5400 dollars. Subtracting babysitting payments from the total gives 8000 - 5400 = 2600 dollars. Zoe therefore made 2600 dollars cleaning pools. The answer is 2600.
Q: Angie is part of a household with shared expenses and contributes $42 a month for necessities. She has a salary of $80 per month. She also pays a share of the household taxes each month. At the end of this month, she had $18 left over. How much did she pay in taxes this month?
A: Angie earned 80 and paid 42 for necessities, so she had 80 - 42 = $38 left. Angie had 18 left after paying taxes, so her share of the taxes was 38 - 18 = $20 this month. The answer is 20.
Question: Harry wants to build a homemade helium balloon with his son, Kevin, so he and Kevin go to the store with $200. They buy a giant sheet to turn into a balloon for $42, a rope for $18, and a propane tank and burner for $14. They plan to use the rest of the money on helium. The helium is $1.50 per ounce. For every ounce they buy, the balloon can fly 113 feet higher. How many feet up can they fly the balloon?
Answer: They have $126 for helium because 200 - 42 - 18 - 14 = 126. They can buy 84 ounces of helium because 126 / 1.5 = 84. They can fly 9,492 feet up because 84 x 113 = 9,492. The answer is 9492.
[Question]The lifespan of a hamster is 6 years less than that of a bat. The lifespan of a frog is 4 times that of a hamster. Altogether, the lifespan of the animals is 30 years. What is the lifespan of the bat?
[Answer]Let’s set up an equation by calling the lifespan of a bat x, and therefore the lifespan of the hamster x – 6, and the lifespan of the frog 4 (x – 6) which add together to equal 30, like this: x + x – 6 + 4 (x – 6) = 30. That gives us 6x – 30 = 30 and we should add 30 to each side to try to isolate the x. Now we have 6x = 60, which we will divide by 6, 6x / 6 = 60 / 6. This gives us x = 10. The bat has a lifespan of 10 years. The answer is 10.
[Question]Stormi is saving up to buy a bicycle. She washes 3 cars for $10 each. She mows 2 lawns for $13 each. If the bicycle she wants costs $80, how much more money does Stormi need to make to afford the bicycle?
[Answer]
The total amount of money from washing cars is 3 * $10 = $30. The total amount of money from mowing lawns 2 * $13 = $26. The total amount of money Stormi makes is $30 + $26 = $56. Stormi still needs to make $80 - $56 = $24. The answer is 24.
