A plant 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.
