Question: Itzayana is 4 inches taller than Zora, who is 8 inches shorter than Brixton. If Zara is 64 inches tall and has the same height as Brixton, calculate the average height of the four people.
Answer: Since Brixton has the same height as Zara which is 64 inches, Zora, who is 8 inches shorter than Brixton, is 64 - 8 = 56 inches tall. Zara and Brixton's height is 64 + 64 = 128 inches. If you add Zora's height, the three have a total height of 128 + 56 = 184. Itzayana is 4 inches taller than Zoran which means she is 56 + 4 = 60 inches tall. The total height of the four friends is 60 + 184 = 244. The average height of the three is 244 / 4 = 61. The answer is 61.

Question: James spends 10 minutes downloading a game, half as long installing it, and triple that combined amount of time going through the tutorial. How long does it take before he can play the main game?
Answer: First divide the download time in half to find the install time: 10 minutes / 2 = 5 minutes. Then add that amount of time to the download time: 5 minutes + 10 minutes = 15 minutes. Then triple that amount of time to find the tutorial time: 15 minutes * 3 = 45 minutes. Then add that time to the install and downtime time to find the total time: 45 minutes + 15 minutes = 60 minutes. The answer is 60.
