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? Let's think first. Chain of thought:
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.
Therefore, the answer is 108.
