Final answer:
Marcus had a net savings of $500 as a result of reducing his insurance coverage to liability only.
Step-by-step explanation:
Marcus James was paying $950 per year for full coverage under an auto insurance policy and then decided to change to a liability coverage only policy that cost $650 per year. To find the net cost or savings to Marcus as a result of reducing his insurance coverage to liability only, we need to calculate the difference between the costs of the two policies and subtract any expenses he incurred after the change.
Cost of full coverage policy: $950 * 3 years = $2850
Cost of liability coverage policy: $650 * 3 years = $1950
Net savings = Cost of full coverage policy - Cost of liability coverage policy - Expenses after changing coverage
Net savings = $2850 - $1950 - $1400 = $500
Therefore, Marcus had a net savings of $500 as a result of reducing his insurance coverage to liability only.
