Answer:
Initial number of trees were 204.
Step-by-step explanation:
555 must be a typo error. The question will not produce correct answer. I worked out with 55 but the answer is wrong. So, the number is 5.
Lets say MacDonald removed 5 orange trees from his farm.
Let t be the initial number of trees
After removing 5 trees, the remaining left are t-5 trees
As given - Each of the remaining trees produced 210 oranges for a total harvest of 41790 oranges. This means
Solving for t:
t = 204
So, initial number of trees were 204.
