Use the following information to answer questions 26-28.

Fran is planning to fence a 10-foot-by-15-foot rectangular plot of ground to use as a garden. She intends to plant a 1-foot-wide border of flowers along the inside of the entire perimeter. The rectangular section surrounded by this border will be planted with vegetables in 11-foot-long rows parallel to the longer sides.

28. When Fran plants the vegetables, she wants the center lines of adjacent rows to be at least 10 inches apart. She also wants the center lines of the outermost rows to be at least 10 inches from the inner edge of the flower border. According to these planting restrictions, what is the maximum number of 11-foot-long rows of vegetables that could be planted within this garden plot?

Answer and Explanation

Your Answer is

Correct Answer is F

Explanation

From the question, it can be known that the interval between two rows of vegetables is 10 inches, and the total width of planting vegetables is (10-2) foot = 96 inches. Since a width of at least 10 inches needs to be reserved with the inner edge, a maximum of 8 rows can be planted. (One row can be planted for a full 20 inches, and two rows can be planted for a full 30 inches... The number of rows that can be planted is the tens digit minus 1)
