In a new housing development, trees are to be planted along the sidewalk of a certain street. Each tree takes up one square foot of sidewalk space, and there are to be 9 feet between each tree. How many trees can be planted if the road is 151 feet long?	Choose the correct choice from the following answers.
A) 8  B) 9  C) 10  D) 11  E) 16
Let T be the number of trees. Then the length required for trees on the sidewalk will be 1*T= T   To maximize the number of trees, the number of 14 feet spaces between trees should be 1 less than total number of trees.   For example, If there are 3 trees, then there should be 2 spaces between them.   So the number of 9 feet spaces will be T-1. Then, the length of sidewalk required for 9 feet spaces will be 9*(T-1)   It is given that total lenght of sidewalk is 151 feet.   or 9(T-1)+T = 151   or 9T-9+T = 151   or 10T = 160   or T=16   Answer:- 16
