An insurance company charges a 35-year old non-smoker an annual premium of $118 for a $100,000 term life insurance policy. the premiums for 45-year olds and 55-year old no smokers are $218 and $563, respectively. write a quadratic model for the premium p as a function of age a.

Step-by-step explanation:

Let premium p for age of a , (p,a)

Let quadratic model be p=Aa²+Ba+C

Substitute the points into equation

-------------(1)

-------------(2)

-------------(3)

Solve system of equation and find out A, B and C using calculator.

Quadratic model:

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
