Let the number of trees be T and the number of plants be P.

The cost for the trees is T*75 = 75T

The cost for the plants is P*6= 6P

The total cost for the plants and the trees is 75T+6P.

The total cost if given 633

==> 75T + 6P = 633............(1)

But, we are also given that P+T = 25 ==> P= 25-T

==> 75T + 6(25-T) = 633

==> 75T + 150 - 6T= 633

==> 69T= 483

==> T= 483/69= 7

==> P= 25-T= 25-7 = 18

Then, she bought 7 trees and 18 plants.
