**Steve**, Wednesday, August 1, 2012 at 4:24pma constant rate in acres/year, or a constant rate as a %age of the glacier's area?

In the first case, it was reduced by 9 acres in 95 years, or .0947 acres/yr

In the second case, it was reduced to 10% in 95 years, at a rate of 2.4%/yr

I guess you want .0947 acres/yr, since it's asking for a linear equation.

A = 10 - .0947x where x=years since 1907.

Extra credit: At that rate, when will the glacier be gone?

**Lori**, Wednesday, August 1, 2012 at 4:31pmYes, I want the .0947 so that I could do the linear equation. Since the linear equation is A=10-.947(95)which means A = 1.0035?

**Lori**, Wednesday, August 1, 2012 at 4:34pmI have to round the .0947 to the nearest thousandth so it would be .09?

**Ms. Sue**, Wednesday, August 1, 2012 at 4:37pmYou rounded to the nearest hundredth.

**Lori**, Wednesday, August 1, 2012 at 4:38pmSo then it is .095?

**Ms. Sue**, Wednesday, August 1, 2012 at 4:39pmRight. 0.095
