She planted eight trees. This means she used half of that amount of apples, which is 8 trees / 2 trees / apple = 4 apples. That means that she planted four of the six apples she bought, leaving only 6 apples - 4 apples = 2 apples to be eaten.
The answer: 2
Reverse engineering the question: Mary bought six apples from the store. From the apples she bought, for each that Mary ate, she planted two trees from the remaining ones. How many apples did Mary eat?
Reasoning and answer: On the third day, 1 / 7 * 280 = 40 students called in sick. If the number of students absent on the second day was twice the number on the third day, then 2 * 40 = 80 students didn't show up for the class on the second day. The total number of students present in the class on the second day was 280 - 80 = 200. If 40 fewer students showed up for the class on the first day than on the second day, then 200 - 40 = 160 students showed up for the class on the first day. The number of students absent on the first day is 280 - 160 = 120. In the three days, the total number of absentees is 120 + 80 + 40 = 240.
The answer: 240
What was the question?
Question: Mr. McNeely takes a register of the total number of students present in class every day. On a particular week, the number of students in the class on the second day was 40 more than the first day. The number of students who didn't turn up for the class on the second day was twice the number of students who didn't turn up on the third day. On the third day, 1/7 of the total number of students of the class called in sick. If the total number of students in the class is 280, calculate the number of absent students in the three days.
The house is 2,400 sq ft and the barn is 1,000 sq ft so it's 2400 + 1000 = 3,400 sq ft. The price is $98 per sq ft and it's 3,400 sq ft big so the property costs 98 * 3400 = $333,200.00.
The answer: 333200
Reverse engineering the question: The price of a home is $98 per square foot (sq ft). The house is 2,400 sq ft and the barn out back is 1,000 sq ft. How much is this property?
Reasoning and answer: They earned 6 x $3 = $18 for the shoes they sold. They earned 18 x $2 = 36 for the shirts they sold. So, they earned $18 + $36 = $54 in total for the clothing they sold. Therefore, Sab and Dane earned $54 / 2 = $27 each.
The answer: 27
What was the question?
Question: Sab and Dane sold 6 pairs of shoes that cost $3 each and 18 shirts that cost $2. How much will each of them earn if they divided their total earning?
Hazel walked 2 x 2 = 4 kilometers in the second hour. So, she walked 2 + 4 = 6 kilometers for 2 hours.
The answer: 6
Reverse engineering the question: Hazel walked 2 kilometers in the first hour. If she walked twice as far in the second hour, how far did she walk for 2 hours?
The six T - shirts cost 6 x $8 = $48. The four sweaters cost 4 x $18 = $72. And five jackets normally cost 5 x $80 = $400. So, a discount of 10 / 100 x $400 = $40 for the five jackets. Thus, the selling price of the five jackets is $400 - $40 = $360. Hence, the total cost of all the items is $48 + $72 + $360 = $480. The sales tax is equal to 5 / 100 x $480 = $24. Therefore, Kevin has to pay $480 + $24 = $504. including the sales tax.
The answer: 504
Reverse engineering the question:
A shopping center sells T-shirts at $8 each, a sweater at $18, and a jacket at $80. The jacket is on sale with a 10% discount. The sales tax is 5%. Kevin wants to buy six T-shirts, four sweaters, and five jackets for his children. How much does Kevin have to pay for all the items, including the sales tax?
