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 14 feet between each tree. How many trees can be planted if the road is 151 feet long?	Answers:
A) 8  B) 9  C) 10  D) 11  E) 12
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 14 feet spaces will be T-1. Then, the length of sidewalk required for 14 feet spaces will be 14*(T-1)   It is given that total lenght of sidewalk is 166 feet.   or 14(T-1)+T = 151   or 14T-14+T = 151   or 15T = 165   or T=11   Answer:- 11
