Reasoning and answer: James starts with 500 Legos and uses half of them, leaving 500 / 2 = 250 Legos unused. He puts those unused Legos away but since he's missing 5 he only puts 250 - 5 = 245 Legos away.

The town had 684 people then had a 25% growth spurt increasing the population by 684 * .25 = 171 people. The town had 684 people then they added 171 people bringing the population to 684 + 171 = 855 people. There were 855 people and 40% moved away so it decreased by 855 * .40 = 342. The population was 855 and 342 people moved away making the new population 855 - 342 = 513 people.
The answer: 513
Reverse engineering the question: Youngsville had a population of 684 people. The town had a growth spurt and the population increased by 25% then they witnessed that 40% of the population moved away. What is the current population?
Reasoning and answer: 20 x 1 / 4 = 5 dolphins are fully trained. So, 20 - 5 = 15 dolphins are not yet fully trained. 15 x 2 / 3 = 10 are currently in training. Therefore, 15 - 10 = 5 dolphins will be trained next month.
The answer: 5

Question: There are 20 dolphins in the aqua park. One-fourth of the dolphins are fully trained. Two-third of the remaining dolphins are currently in training and the rest will be trained next month. How many dolphins will be trained next month?
Loisa will pay a total of $40 x 4 = $160 for the first 4 months. She will pay a total of $35 x 4 = $140 for the next four months. And she will pay a total of $30 x 4 = $120 for the last four months. Thus, she will pay a total of $100 + $160 + $140 + $120 = $520 for 12 months including the down payment. Therefore, Loisa can save $520 - $450 = $70 if she buys the tablet in cash.
The answer: 70
Reverse engineering the question: Loisa wants to buy a tablet that costs $450 cash. Since she does not have enough money, the store offered her an installment plan for 12 months. She will pay $100 as a down payment and pay $40 for the first 4 months; then $35 for the next four months; then $30 for the last four months. How much will Loisa save if she will buy the tablet in cash instead of on installment?
Reasoning and answer: If the business's stock price rises 30%, then his share on the company is worth 30% multiplied by $2000 plus $2000 that he already had. That results in 30% * $2000 + $2000 = $600 + $2000 = $2600. Since he already had $300, with $2600 more he will have $300 + $2600 = $2900.
The answer: 2900
