Step-by-step reasoning process: 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.
[Q & A] 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?
The answer is 520

Step-by-step reasoning process: Since a month has four weeks, the tree will increase its height by 2 feet for 4 * 4 = 16 weeks after four months of growing. Since the tree grows at 2 feet per week, after 16 weeks, the tree would have increased its height by 2 * 16 = 32 feet. If the tree is currently 10 feet tall, its height after four months will be 10 + 32 = 42 feet.
[Q & A] The question is Josue planted a tree in his backyard that grows at the rate of 2 feet per week. If the tree is currently 10 feet tall, what would be the tree's total height after 4 months (assuming each month is 4 weeks long)?
The answer is 42

Step-by-step reasoning process: If the experienced sailors received 1 / 5 times more money than the inexperienced sailors, they were paid 1 / 5 * 10 = $2 more. The total hourly earnings for the experienced sailors each is $10 + $2 = $12. In a 60 - hour workweek, an experienced sailor is paid 60 * $12 = $720. In a month, an experienced sailor is paid 4 * $720 = $2880. If there were five inexperienced sailors, the total number of experienced sailors was 17 - 5 = 12. If each experienced sailor was paid $2280 per month, the total combined monthly earnings for the experienced is 12 * 2880 = $34560.
