Chapter 6.6, Problem 14P

When Mary converted a recipe from metric measurements to U.S. customary measurements, she discovered that she needed 8.63 cups of flour. Mary has a 1-cup measure, a $\frac{1}{2}-$ cup measure, a $\frac{1}{4}-$ cup measure, and a measuring tablespoon, which is $\frac{1}{16}$ cup. How should Mary use her measuring implements to measure the 8.63 cups of flour as accurately and efficiently as possible? Explain your reasoning.
