Question: Renne earns $4000 per month and wants to save half of her monthly earnings to buy the vehicle of her dreams worth $16000. How many months of saving will it take her to buy the vehicle?
Answer: If she's saving half her salary every month, she saves 1 / 2 * $4000 = $2000 every month. If the vehicle is worth $16000, and she saves $2000 every month to buy it, she will have to save for 16000 / 2000 = 8 months. The answer is 8.

Question: The bowl of fruit contains apples, pears, and bananas. There are two more pears than apples, and three more bananas than pears. If the bowl contains 19 pieces of fruit, how many bananas does it contain?
Answer: Let A be the number of apples. There are A + 2 pears. There are (A + 2) + 3 pears. Then A + (A + 2) + ((A + 2) + 3) = 19. 3A + 7 = 19. 3A = 12. A = 4. There are 4 apples. There are (4 + 2) + 3 = 9 bananas. The answer is 9.
