Fionna is looking at saving some money on her car insurance. She drives a Nissan Murano worth $35,000. If she increases her deductible from $500 to $1,000, her annual savings on her premium could be 9 percent. If her annual premium is $2,000, how many years would she have to be incident free in order to justify the higher deductible (assume no interest for simplicity). Is it worth it? Now what if her car was a Pontiac Vibe worth only $2,500?
