1. ''A glacier is built up over time when more snow falls than melts each year. One glacier in Alaska was estimated to accumulate 5km3 of ice each winter, but would lose 14of its total ice the following summer. At the start of summer 2005, the glacier had 27km3 of ice. How much ice would the glacier have in 2012 if this trend continued?"

(a) Identify the varying quantities in this scenario.

(b) Define a variable for each varying quantity.

(c) Use your variables to create a table that you will use to solve this problem. Then solve the problem. (d) Show on a number line the change in the volume of the ice each year.

(e) Determine if the volume of the ice changes with a constant rate of change with respect to the time since summer 2005.
