The height in inches (h) of a tomato plant growing in a garden is given by the equation h=2t+3, where t represents time in days. when will the tomato plant be between 13 and 27 inches?

since h=2t+3 i.e. at h=13 we find 13= 2t+3
 i.e. 13-3= 2t
10=2t i.e. t=10/2
 i.e. t=5 days
similarly at h=27
we find 27= 2t+3
 i.e. 27-3= 2t
24=2t i.e.
t=24/2 i.e.
t=12 days
hence in 5 and 12 days the height of the tomato plant will be between 13 and 27 inches respectively.
