Chapter $3$ Question $23$ Page $132$

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 household.

The equation is

y $=850-\mathrm{.}1$xy $=$ Insurance needed $($$$000)$

x $=$ Current Age of Head of Household

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 $30$ years old.

$$847,000$

$$857,000$

$$843,000$

$$853,000$
