A driver needs new tires for her car and is trying to decide if she should purchase low rolling resistance tires. The regular tires cost $300 (for all 4 tires) and will last 3 years. The low rolling resistance tires cost $400 and will also last 3 years, saving $50 per year in gas.

What is the NPV for choosing the low rolling resistance tires if the expected return she is getting on her investments is 10%?
