6-44.

The cost of a 55 inch HDTV is decreasing 15% per year.

What is the multiplier?

If the cost decreased by 15% each year, the newcost would be 85% of the previous year.

0.85

If the current cost of the HDTV is $1500, what will it cost in four years?

In one year the cost will be $1500(0.85).

In two years the cost will be [$1500(0.85)](0.85).

Continue this pattern.If the current cost of the HDTV is $1500, write an equation for the cost in

*n*years.Use the pattern in part (b) to write your equation.
