1. The cost of a 55 inch HDTV is decreasing 15% per year. Homework Help ✎

1. What is the multiplier?

2. If the current cost of the HDTV is $1500, what will it cost in four years? 3. If the current cost of the HDTV is$1500, write an equation for the cost in n years.

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

0.85

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.

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