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?
Please answer the following question by reasoning step-by-step.
32
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
