Q: Jerry was asked by her mom to do grocery shopping. He needs to buy 2 liters of mustard oil that costs $13 per liter, 3 pounds of gluten-free penne pasta that costs $4 per pound, and 1 pound of pasta sauce that costs $5. If Jerry can keep the rest of the $50 after grocery shopping, how much money will he have?
A: The cost of 2 liters of mustard oil is $13 x 2 = $26. The cost of 3 pounds of gluten - free penne pasta is $4 x 3 = $12. So, Jerry spent a total of $26 + $12 + $5 = $43 for grocery shopping. Thus, Jerry will have $50 - $43 = $7 for himself. The answer is 7.
Question: Ivar owns a stable. He recently has 3 horses and each horse consumes 5 liters of water for drinking and 2 liters for bathing per day. If he added 5 horses, how many liters of water does Ivar need for all the horses for 28 days?
Answer: The total horse he owns is 5 + 3 = 8. The total liters of water each horse consumes is 5 + 2 = 7. So, the total water all the horses consume every day is 7 x 8 = 56. And the total of liters of water they consume every week is 56 x 7 = 392. Therefore, the total liters of water they consume for the entire month is 392 x 4 = 1568. The answer is 1568.
[Question]Yesterday, Sarah collected 50 aluminum cans while Lara collected 30 more aluminum cans. Today, Sarah collected 40 while Lara collected 70 aluminum cans. How many fewer cans did they collect today than yesterday?
[Answer]Yesterday, Lara collected 50 + 30 = 80 aluminum cans. So Sarah and Lara collected a total of 50 + 80 = 130 aluminum cans yesterday. Today, Sarah and Lara collected a total of 40 + 70 = 110 aluminum cans. Thus, they collected 130 - 110 = 20 fewer aluminum cans today than yesterday. The answer is 20.
Q: A class composed of 12 girls and 10 boys was sent to the library for their reading class. Their teacher found out that only 5/6 of the girls and 4/5 of the boys are reading. How many students are not reading?
A: There are 12 x 5 / 6 = 10 girls who are reading. So, 12 - 10 = 2 girls are not reading. There are 10 x 4 / 5 = 8 boys who are reading. So, 10 - 8 = 2 boys are not reading. Thus, there are a total of 2 girls + 2 boys = 4 students who are not reading. The answer is 4.
