Question

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?

Answer 1

13 < 2t + 3 < 27

13<2t+3                 2t+3<27
13-3<2t                  2t<27-3
10<2t                     2t<24
10/2<t                    t<24/2
5<t                         t<12
  
  5 < t < 12
