A certain mountain has an elevation of 19,402sq.ft. In 1903, the glacier in this peak covered 7 acres. By 2000 this glacier had melted to only one acre.

A.) Assume that the glacier melted at a constant rate each year. Find this yearly rate

B.) Use the answer from part A to write a linear equation that gives the acreage A of this glacier years past 1903

In 97 years, it melted 6 acres. Right?

anonymous · Answer

yes

nory · Answer

So I believe the yearly rate would be 6/97. Right?

anonymous · Answer

7/97?

nory · Answer

Why 7?
It went from 7 acres to 1 acre, and 7 - 1 = 6.
You could be right, though.
But I think it's 6.
