I posted this earlier and they gave me this answer it's WRONG PLS WORK IT OUT IN A HURRY AND CORRECT?

A new electronic process monitor costs $990,000. This cost could be depreclated at 30% per year (Class 10 ). The monitor would actually be worthless in five years. The new monitor would save $460,000 per year before taxes and operating costs. If we require a 15% return, what is the NPV of the purchase? Assume a tax rate of 40%. (Do not round intermediate calculations. Round the final answer to 2 decimal places. Omit $ sign in your response.)
