Come up with a question and reasoning that would justify [140] as the answer.
The question is: The average temperature in Orlando in a particular week was 60 degrees. If the temperature on each of the first 3 days in that week was 40, and the temperature for Thursday and Friday was 80 degrees each, calculate the total temperature of the remaining days of that week.
Reasoning: If the average temperature of Orlando for the week was 60, then the total temperature for the week was 7 * 60 = 420 degrees. For the first three days of that week, the temperature was 40 degrees each day, totaling 3 * 40 = 120 degrees in the three days. The temperature for Thursday and Friday was 80 degrees each, a total of 80 * 2 = 160 degrees. The temperature of Orlando for the first five days was 160 + 120 = 280 degrees. The temperature for the remaining two days is 420 - 280 = 140 degrees.

Come up with a question and reasoning that would justify [70] as the answer.
The question is: John has 3 bedroom doors and two outside doors to replace. The outside doors cost $20 each to replace and the bedroom doors are half that cost. How much does he pay in total?
Reasoning: The outside doors cost 2 * $20 = $40. Each indoor door cost $20 / 2 = $10. So all the indoor doors cost $10 * 3 = $30. That means the total cost is $40 + $30 = $70.

Come up with a question and reasoning that would justify [520] as the answer.
The question is: Tara has been planning to buy a laptop which costs $1000. A computer shop accepts payment in installments of $65 per month provided that a 20% down payment is made. If Tara wants to pay an additional $20 for the down payment, how much will her balance be after paying for 4 months?
Reasoning: Tara has to make a $1000 x 20 / 100 = $200 down payment. Since Tara wants to pay $20 more for the down payment, her total down payment will be $200 + $20 = $220. So her remaining balance payable over a year is $1000 - $220 = $780. Tara has to make a monthly payment of $780 / year / 12 months / year = $65 / month. The total cost of her payments for 4 months is $65 / month x 4 months = $260. Therefore, Tara's balance after 4 months is $780 - $260 = $520.
