[Question]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?
[Answer]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.

[Question]Leon ordered 3 sets of toy organizers for $78 per set and 2 gaming chairs for $83 each. If there is a delivery fee that is 5% of the total sales, how much did Leon pay?
[Answer]Three sets of toy organizers cost $78 x 3 = $234. Two gaming chairs cost $83 x 2 = $166. Leon's total orders amount to $234 + $166 = $400. Then, the delivery fee is $400 x 5 / 100 = $20. So, Leon had to pay a total of $400 + $20 = $420. The answer is 420.

[Question]The Parker family needs to leave the house by 5 pm for a dinner party. Mrs. Parker was waiting to get into the bathroom at 2:30 pm. Her oldest daughter used the bathroom for 45 minutes and her youngest daughter used the bathroom for another 30 minutes. Then her husband used it for 20 minutes. How much time will Mrs. Parker have to use the bathroom to leave on time?
[Answer]
