This problem requires about 8 nickels, 8 quarters, and a sheetof 8.5-by-11-inch paper. The goal is to estimate the diameter ofeach type of coin as follows: Using trial and error, find a combinationof nickels and quarters that, when placed side by side,extend the height (long side) of the paper. Then do the same alongthe width (short side) of the paper. Use the information obtainedto write two linear equations involving the unknown diametersof each type of coin, then solve the resulting system to find thediameter for each type of coin.
