[Question]Joan is answering English and Math exams with 30 and 15 questions, respectively. The English exam is to be completed in 1 hour and the Math exam in 1.5 hours. If Joan wants to spend an equal amount of time on each question, how many more minutes does she have in answering each question on the Math exam than the English exam?
[Answer]Joan is given 1 x 60 = 60 minutes to answer the English exam. So Joan will spend 60 / 30 = 2 minutes for each English question. She is given 1.5 x 60 = 90 minutes to answer the Math exam. So, she will spend 90 / 15 = 6 minutes for each Math question. Hence, Joan has 6 - 2 = 4 minutes more for answering each question in Math than in English. The answer is 4.
Q: Safari National park has 100 lions, half as many snakes, and 10 fewer giraffes than snakes. On the other hand, Savanna National park has double as many lions as Safari National park, triple as many snakes as Safari National park, and 20 more giraffes than Safari National park. How many animals in total does Savanna National park have?
A: Safari National park has 1 / 2 * 100 = 50 snakes. Safari National park has 50 - 10 = 40 giraffes. Savanna National park has 100 * 2 = 200 lions. Savanna National park has 50 * 3 = 150 snakes. Savanna National park has 40 + 20 = 60 giraffes. Savanna National park has a total of 200 + 150 + 60 = 410 animals. The answer is 410.
Question: To support the school outreach program, Einstein wants to raise $500 by selling snacks. One box of pizza sells for $12, a pack of potato fries sells for $0.30, and a can of soda at $2. Einstein sold 15 boxes of pizzas, 40 packs of potato fries, and 25 cans of soda. How much more money does Einstein need to raise to reach his goal?
Answer: Einstein collected 15 x $12 = $180 for selling pizzas. He collected 40 x $0.30 = $12 for the 40 packs of potato fries. He collected 25 x $2 = $50 for the 25 cans of soda. Thus, the total amount section Einstein collected was $180 + $12 + $50 = $242. Therefore, Einstein needs $500 - $242 = $258 more to reach the goal. The answer is 258.
[Question]Susan is making jewelry with a repeating pattern that has 3 green beads, 5 purple beads, and twice as many red beads as green beads. If the pattern repeats three times per bracelet and 5 times per necklace, how many beads does she need to make 1 bracelets and 10 necklaces?
[Answer]First find the number of red beads per repeat: 3 green * 2 red / green = 6 red. Then add the number of beads of each color to find the total number of bead per repeat: 6 beads + 3 beads + 5 beads = 14 beads. Then multiply the number of beads per repeat by the number of repeats per bracelet to find the number of beads per bracelet: 14 beads / repeat * 3 repeats / bracelet = 42 beads / bracelet. Then multiply the number of beads per repeat by the number of repeats per necklace to find the number of beads per necklace: 14 beads / repeat * 5 repeats / necklace = 70 beads / necklace. Then multiply the number of beads per necklace by the number of necklaces to find the total number of beads used in the necklaces: 70 beads / necklace * 10 necklaces = 700 beads. Then add the number of beads used in a bracelet to the number of beads in the necklaces to find the total number of beads used: 700 beads + 42 beads = 742 beads. The answer is 742.
Q: There is a pie-eating contest at school. Adam eats three more pies than Bill. Sierra eats twice as many pies as Bill. If Sierra ate 12 pies, how many pies were eaten in total?
A: Bill ate 12 / 2 = 6 pies. Adam ate 6 + 3 = 9 pies. They ate a total of 6 + 9 + 12 = 27 pies. The answer is 27.
Question: Maiya has two sisters. The first sister is twice as old as Maiya. The first sister is 1 year younger than Maiya. Their average age is 5. How old is Maiya?
Answer:
Their total age is 15 because 3 x 5 = 15. 15 - X - 2X - (X - 1) is equivalent to 16 = 4X. Maiya is 4 years old because 16 / 4 = 4. The answer is 4.
