Q: There are four growing trees. The first tree grows 1 meter/day, the second grows the same amount in half the time, the third grows 2 meters/day, and the fourth tree grows a meter more than the third each day. How many meters did the trees grow in total in 4 days?
A: The second tree grows 1 * 2 = 2 meters a day. The fourth tree grows 2 + 1 = 3 meters a day. The first tree grows 4 * 1 = 4 meters in 4 days. The second tree grows 2 * 4 = 8 meters in 4 days. The third tree grows 2 * 4 = 8 meters in 4 days. The fourth tree grows 3 * 4 = 12 meters in 4 days. In 4 days, all four trees grew 4 + 8 + 8 + 12 = 32 meters combined. The answer is 32.
