A certain mountain has an elevation of 19,273 feet. In 1921, the glacier on this peak covered 4 acres. By 2001 this glacier had melted to only 1 acre. (a) Assume that this glacier melted at a constant rate each year. Find this yearly rate. (b) Use your answer from part (a) to write a linear equation that gives the acreage A of this glacier t years past 1921.
