Long-Life Insurance has developed a linear model that it uses to determine the amount of term life insurance a family of four should have, based on the current age of the head of the household. The equation is: y=1610.35x where y=Insuranceneeded($000)x=Currentageofheadofhousehold b. Use the equation to determine the amount of term life insurance to recommend for a family of four if the head of the household is 51 years old. (Round your answer to 2 decimal places.)
