tresset_1 [31]
The first thing we are going to do for this case is to define the following variable:
 x = number of trees.
 We then have that the equation that represents the problem is given by:
 y = 50 (x-1) + 20
 Rewriting:
 y = 50x - 50 + 20
 y = 50x - 30
 Substituting for y = 390 we have:
 390 = 50x - 30
 We clear x:
 x = (390 + 30) / (50)
 x = 8.4
 nearest whole integer
 x = 8
 Answer:
 
will be planted along one block about 8 trees.
