[Question]Marly has ten $20 bills, eight $10 bills, and four $5 bills. If she wants to change her bills to $100 bills, how many pieces of $100 bills will she have?
[Answer]The ten $20 bills amount to $20 x 10 = $200. The eight $10 bills amount to $10 x 8 = $80. The four $5 bills amount to $5 x 4 = $20. So, Marly has a total of $200 + $80 + $20 = $300. Therefore, she will have $300 / $100 = 3 pieces of $100 bills. The answer is 3.
Q: Ella has 4 bags with 20 apples in each bag and six bags with 25 apples in each bag. If Ella sells 200 apples, how many apples does Ella has left?
A: 4 bags have 4 x 20 = 80 apples. And, six bags have 6 x 25 = 150 apples. Thus, Ella has 80 + 150 = 230 apples in all. Therefore, Ella has 230 - 200 = 30 apple left. The answer is 30.
Question: Jackson is buying chairs for his restaurant. He has 6 tables with 4 seats and 12 tables with 6 seats. How many chairs total does Jackson need to buy?
Answer: First find how many chairs Jackson needs for the four - seat tables by multiplying the number of four - seat tables by 4: 4 chairs / table * 6 tables = 24 chairs. Next find how many chairs Jackson needs for the six - seat tables by multiplying the number of six - seat tables by 6: 6 chairs / table * 12 tables = 72 chairs. Now add the number of chairs for the four - and six - seat tables to find the total number of chairs Jackson needs: 24 chairs + 72 chairs = 96 chairs. The answer is 96.
[Question]Casey takes 6 hours to complete a marathon race, while Zendaya takes 1/3 times longer to cover the same distance. What is the average time the two take to complete to race?
[Answer]Zendaya takes 1 / 3 * 6 hours = 2 hours longer to complete the marathon. To complete the marathon, Zendaya takes 6 hours + 2 hours = 8 hours. The combined time the two take to complete the marathon is 8 hours + 6 hours = 14 hours. The average number of hours Casey and Zendaya take to complete the marathon is 14 hours / 2 people = 7 hours / person. The answer is 7.
Q: Darry is a roofer and has to climb ladders multiple times a day. He climbs his full ladder, which has 11 steps, 10 times today. He also climbs his smaller ladder, which has 6 steps, 7 times today. He did not climb any steps otherwise. In total, how many times has Darry climbed a step today?
A: Climbing the full ladder means Darry has climbed 11 steps * 10 times = 110 steps so far. On his smaller ladder, he has climbed 6 steps * 7 times = 42 steps. So he has climbed a step a total of 110 + 42 = 152 times today. The answer is 152.
Question: Janet has 9 cards more than Brenda. Mara has twice as many cards as Janet. How many cards do they have in all if Mara has 40 cards less than 150?
Answer:
Mara has 150 - 40 = 110 cards. Janet has 110 / 2 = 55 cards since Mara has twice as many as Janet. Brenda has 55 - 9 = 46 cards since Janet has 9 cards more than Brenda. Therefore, they all have 110 + 55 + 46 = 211 cards. The answer is 211.
