Find the initial number of orange trees on MacDonald's farm.

Answer 1

Suppose t would be the initial number of trees

"remove 5 trees at the beginning of the season" means (t - 5) stay

"every remaining tree made 210 oranges for a total of 41,790 oranges" means(t - 5) * 210 = 41790 Now, you can solve for t:

(t-5)(210) = 41790

210t - 1050 = 41790

210t = 42840

t = 204 At start there were 204 trees. After 5 were cut, the 199 that had remained, made 210 oranges each for an amount of 199*210 = 41790 oranges.
