There are 8 x 3 = 24 indoor chairs. There are 12 x 3 = 36 outdoor chairs. In total there are 24 + 36 = 60 chairs.
The answer: 60

There were 2 * 500 = 1000 people at the counting station who were counted on the first day. In the two days, 1000 + 500 = 1500 were counted at the station.
The answer: 1500
Reverse engineering the question: At a people counting station, the number of people counted on the first day was twice the total number counted on the second day. If 500 people were counted on the second day, how many people were counted on the two days?


Reasoning and answer: Carl saved in 6 weeks $25 / week x 6 weeks = $150. On the seventh week, he ended up having to pay in bills $150 / 3 = $50. His savings were then $150 - $50 = $100. His dad gave him $170 – $100 = $70.
The answer: 70
What was the question?
Question: Carl wants to buy a new coat that is quite expensive. He saved $25 each week for 6 weeks. On the seventh week, he had to use a third of his saving to pay some bills.

10 minutes for 5 miles means 10 minutes / 5 miles = 2 minutes / mile. 1 hour is 60 minutes so 60 minutes / hour / 2 minutes / mile = 30 miles / hour.
The answer: 30
Reverse engineering the question: Marcos has to get across a 5 mile lake in his speedboat in 10 minutes so he can make it to work on time. How fast does he need to go in miles per hour to make it?


Let x be Luna's house rental budget. The total budget for house and food rental is represented by the equation x + (60x / 100) = 240. The equation becomes 100x + 60x = 24000 after multiplying each term by 100 to get rid of the fraction. By combining like terms, the equation becomes 160x = 24000. Thus, the value of x is 24000 / 160 = 150 which represents the house rental budget. So, Luna's food budget is $240 - $150 = $90. Her phone bill budget is $90 x 10 / 100 = $9. Therefore, Luna's monthly budget for all those expenses is $240 (house and food) + $9 (phone) = $249.
The answer: 249
Reverse engineering the question:
Luna's monthly food budget is equal to 60% of her house rental budget while her phone bill budget is 10% of her food budget. If the total budget of house rental and food budget is $240, how much is Luna's total monthly budget to pay all those expenses?
