Tina saved $27 in June, $14 in July, and $21 in August. Then Tina spent $5 on books and $17 on new shoes. How much money does Tina have left? Give the rationale and then the answer.
Let's think step by step. The total amount of money saved is $27 + $14 + $21 = $62. The total amount spent on books and new shoes is $5 + $17 = $22. Tina has $62 − $22 = $40 left.. The answer is: 40.

Carson needs to mow the lawn and plant some flowers. Carson has to mow 40 lines to cover the whole yard, and it takes him 2 minutes to mow one line. He also needs to plant 8 rows of flowers, each with 7 flowers, and it takes him half a minute to plant each flower. How many minutes will Carson spend gardening? Give the rationale and then the answer.
Let's think step by step. First find the total time Carson spends mowing: 40 lines * 2 minutes / line = 80 minutes. Then find the total number of flowers Carson plants: 8 rows * 7 flowers / row = 56 flowers. Then multiply that number by the time taken to plant each flower to find the total time spent planting flowers: .5 minutes / flower * 56 flowers = 28 minutes. Finally, add that time to the time spent mowing to find the total time spent gardening: 28 minutes + 80 minutes = 108 minutes.. The answer is: 108.

Alden had 50 nephews ten years ago. This is half the number of nephews Alden has now. If Vihaan has 60 more nephews than Alden now, how many nephews do the two have altogether? Give the rationale and then the answer.
Let's think step by step. If the number of nephews Alden had 50 years ago is half the number of nephews he has now, Alden has 50 * 2 = 100 nephews. Vihaan has 60 more nephews than Alden, meaning currently Vihaan has 100 + 60 = 160 nephews. Altogether, the two have 160 + 100 = 260 nephews.. The answer is: 260.
