Leonard is 4 years younger than Nina who is half as old as Jerome. If the sum of their ages is 36, what is Leonard's age?
Let's think: Let x be the age of Nina. So, Leonard's age is x - 4. And Jerome's age is 2x. Since the sum of their ages is 36, then the equation is x + x - 4 + 2x = 36. By combining like terms, the equation becomes 4x = 40. So the value of x which represents the age of Nina is x = 40 / 4 = 10. Therefore, Leonard is 10 - 4 = 6 years old.. The answer is: 6.

Bob has planted corn in his garden, and it has just started to sprout. A week after planting it, it had grown 2 inches. The next week, its height increased by twice as much as it had the first week. In the third week, it grew 4 times as much as it did the week before. How tall are the corn plants now?
Let's think: The second week it grew twice as much as the first week, so 2 * 2 inches = 4 inches. The third week it grew 4 times as much as in the second week, so 4 * 4 inches = 16 inches. In total, it grew 2 inches + 4 inches + 16 inches = 22 inches.. The answer is: 22.

There are 30 major league baseball stadiums. Zach has a goal to take his son to see at least one game at each one. He has calculated the average cost for them to travel and see a game will be $900 per stadium. Zach can save $1,500 per year for his baseball stadium trips. How many years will it take Zach to accomplish his goal?
Let's think: The total cost would be $900 x 30 stadiums = $27,000. Dividing the total cost by the amount Zach saves per year, we get $27,000 / $1,500 / year = 18 years.. The answer is: 18.

Hayden eats 1 oz of mixed nuts as an evening snack. He buys the bulk bag of mixed nuts that cost $25.00 a bag and holds 40 oz of mixed nuts. There is currently a $5.00 coupon for this item. How much will each serving of nuts cost, in cents, after the coupon is applied?
Let's think:
The nuts are $25.00 and he has a $5.00 coupon, so the nuts are on sale for $25 - $5 = $20.00. He eats 1 oz of nuts every evening and the bag has 40 oz of nuts, so it has 40 / 1 = 40 1 oz servings. The nuts cost $20.00 and there are 40 servings per bag, so his snack is $20 / 40 = $0.50 per serving.. The answer is: 50.
