solve the problem.\n12) suppose a life insurance policy costs $24 for the first unit of coverage and then $6 for each additional unit of coverage. let c(x) be the cost for insurance of x units of coverage. what will 10 units of coverage cost?

Answer

Explanation:

Step1: Identify the base - cost and additional - unit cost

The first - unit cost is $24, and the cost per additional unit is $6.

Step2: Calculate the number of additional units

For 10 units of coverage, the number of additional units beyond the first one is $x - 1=10 - 1 = 9$.

Step3: Calculate the cost of additional units

The cost of the 9 additional units is $6\times9 = 54$.

Step4: Calculate the total cost

The total cost $C(10)$ is the sum of the first - unit cost and the cost of additional units. So $C(10)=24 + 54$. $C(10)=78$.
