Allison bought a Blu-ray DVD player from the store for $275 that came with a one-year warranty. At checkout, she was asked if she would like to buy a two-year extended warranty that would replace her DVD player with an identical one if it broke down. The extended warranty costs $70, and Allison expects that the DVD player will depreciate in value by $50 every year as new models come out (this means a replacement would cost $175 after 2 years and $125 after 3 years).

Suppose Allison pays for the purchase of the extended warranty with her credit card, which has a 5 percent interest rate. Also assume that Allison knows there is a 10 percent chance that the DVD player will break in any given year.

The present value of buying the extended warranty is $ ___ (Round your response to two decimal places and use a minus sign if necessary.)
