Aplant 8 inches tall is placed by a window. if it grows 3 inches a day, how many days will it take 26 inches tall?

Height=original height+grouth
origial height=8
grouth=height grown per da time number of days=3d

26=desired height
26=8+3d
minus 8 from both sides
18=3d
divide both sides by 3
6=d

6 days

Height of the plant  before placing by a window = 8 inches
The number of days required by the plant to increase 3 inches = 1 day
Now the length of the actual plant has to be deducted from 26 inches.
Length by which the plant
actually grows after putting it by the window = 26 - 8
                                                                      = 18 inches
So
The number of days required by
the plant to increase by 18 inches = 18/3 days
                                                       = 6 days
So the plant will require 6 days to reach a length of 26 inches.
