A checker board has 64 squares. Each checker is 1/4 inch thick. If you place 1 checker on one corner of the checker board, then stack 2 checkers on the second square; then 4 on the third square; continuing until you get to the 64th square, how high will the stack of checkers be which is placed on the 64th square? [HINT: Make a t-chart to inspect this pattern, then develop the exponential function which uses "the square number" as input, and calculates "the number of checkers on that square" as output.] A. About 60,000 miles high

B. Roughly 35 times the diameter of the Earth

C. All the given answers are much too high

D. Between 9,000,000 and 10,000,000 feet high

E. Almost 200,000 round trips to the Sun (from Earth)
