A certain mountain has an elevation of 19,269 feet. In 1906, the glacier on this peak covered 4 acres. By 2005 this glacier had melted to only 1 acre. Assume that this glacier melted at a constant rate each year. Find this yearly rate. Use your answer from part (a) to write a linear equation that gives the acreage A of this glacier t years past 1906. The yearly rate of change is acres/year. (Type an integer or a decimal. Round to the nearest thousandth.) What is the equation that gives the acreage of the glacier t years after 1906? A=
