Question: Susan wants to throw a party for her mom. She is planning on having 30 guests. For dinner she is making a recipe that makes 2 servings each. Each batch of the recipe calls for 4 potatoes and 1 teaspoon of salt. A potato costs $.10 and a container of salt costs $2 at the supermarket. If each container of salt has 5 teaspoons, how much money will Susan spend on food?
Answer: Susan needs to make 30 / 2 = 15 batches of the recipe. Therefore, she will need 15 * 4 = 60 potatoes. She will also need 1 * 15 = 15 teaspoons of salt. Thus she will have to buy 15 / 5 = 3 containers of salt. Therefore, she will spend 60 * $.1 = $6 on potatoes and 3 * $2 = $6 on salt. Thus, she will spend $6 + $6 = $12 on food. The answer is 12.

Question: Annie is a mother of 3 children: Mark, Matt, and Mike. She decided to give them some fruits. Mike received 3 oranges. Matt got twice as many apples, and Mark got as many bananas as Mike and Matt received fruits altogether. How many fruits do the three children have in total?
Answer: Mike received 3 oranges. Matt received twice as many apples as Mike received oranges, so he got 3 * 2 = 6 apples. Mark received 6 + 3 = 9 bananas. So in total, all children received 3 + 6 + 9 = 18 fruits. The answer is 18.

Question: Luna's monthly food budget is equal to 60% of her house rental budget while her phone bill budget is 10% of her food budget. If the total budget of house rental and food budget is $240, how much is Luna's total monthly budget to pay all those expenses?
Answer: Let x be Luna's house rental budget. The total budget for house and food rental is represented by the equation x + (60x / 100) = 240. The equation becomes 100x + 60x = 24000 after multiplying each term by 100 to get rid of the fraction. By combining like terms, the equation becomes 160x = 24000. Thus, the value of x is 24000 / 160 = 150 which represents the house rental budget. So, Luna's food budget is $240 - $150 = $90. Her phone bill budget is $90 x 10 / 100 = $9. Therefore, Luna's monthly budget for all those expenses is $240 (house and food) + $9 (phone) = $249. The answer is 249.

Question: A company has 200 employees. 60% of the employees drive to work. Of the employees who don't drive to work, half take public transportation. How many more employees drive to work than take public transportation?
Answer:
Drive to work:200(.60) = 120. Don't Drive to work:200 - 120 = 80. Public Transportation:80(.50) = 40 employees. 80 - 40 = 40 employees. The answer is 40.
