[Answer]The first 8 customers bought 8 * 3 = 24 cases. The next 4 customers bought 4 * 2 = 8 cases. The last 8 customers bought 8 * 1 = 8. In total 24 + 8 + 8 = 40 cases were sold. The answer is 40.
Q: Elvis and Ralph are to make square shapes with matchsticks from a box containing 50 matchsticks. Elvis makes 4-matchstick squares and Ralph makes 8-matchstick squares. If Elvis makes 5 squares and Ralph makes 3, how many matchsticks will be left in the box?
A: Elvis makes 5 squares with 4 matchsticks each for a total of 5 * 4 = 20 matchsticks. Ralph makes 3 squares with 8 matchsticks each for a total of 8 * 3 = 24 matchsticks. They used a total of 20 + 24 = 44 matchsticks. There will be 50 - 44 = 6 matchsticks left in the box. The answer is 6.
Question: An online website offers a flat rate shipping price of $5.00 if the purchase is below $50.00. If it's above $50.00 then they will charge 20% of the purchase price for shipping. Thomas orders 3 shirts for $12.00 each, a pack of socks for $5.00, 2 pairs of shorts for $15.00 each and a pair of swim trunks for $14.00 How much will his total bill be, including shipping?
Answer: He orders 3 shirts at $12.00 each for a total of 3 * 12 = $36.00. He orders 2 pair of shorts for $15.00 each for a total of 2 * 15 = $30.00. He spends $36.00 on shirts, $5.00 on socks, $30.00 on shorts and $14.00 on a pair of swim trunks for a total of 36 + 5 + 30 + 14 = $85.00. His order is over $50.00 so he will be charged 20% shipping on his $85.00 order so he'll pay .20 * 85 = $17.00 in shipping. His order is $85.00 and he's paying $17.00 in shipping for a total bill of 85 + 17 = $102.00. The answer is 102.
[Question]John is half times younger than his father, who is 4 years older than John's mother. If John's father is 40 years old, what's the age difference between John and his mother?
[Answer]John is half times his father's age. Thus 1 / 2 * 40 = 20 years. Since the mother is 4 years younger than the father, she is 40 - 4 = 36 years old. The age difference between John and his mother is 36 - 20 = 16 years. The answer is 16.
Q: The school decided to add 20% to the gym budget. In a normal month, they could buy 15 dodgeballs for $5 each if they spent the entire budget on that. If they only buy softballs instead, which cost $9 each, how many can they buy with the new budget?
A: The old budget was $75 because 15 x 5 = 75. They are adding $15 to the budget because 75 x .2 = 15. The new budget is $90 because 75 + 15 = 90. They can buy 10 softballs on the new budget because 90 / 9 = 10. The answer is 10.
Question: On Tuesday, Liza had $800 in her checking account. On Wednesday, she paid her rent, $450. On Thursday, she deposited her $1500 paycheck. On Friday, she paid her electricity and internet bills which were $117 and $100, respectively. Then on Saturday, she paid her phone bill, $70. How much money is left in Liza's account?
Answer:
On Wednesday, Liza had $800 - $450 = $350 left in her account. After depositing on Thursday, she had $350 + $1500 = $1850 in her account. On Friday, she paid a total of $117 + $100 = $217 for her electricity and internet bills. So, $1850 - $217 = $1633 was left on her account on Friday. After paying her phone bill, Liza has $1633 - $70 = $1563 left in her account. The answer is 1563.
