Answer :

To find Cindy's new annual premium including the discount, let's follow a detailed, step-by-step solution:

1. Calculate the Total Original Annual Premium:
To find the total cost of her original premiums, sum up the individual annual premiums:

[tex]\[ \text{Bodily Injury} = \$ 31.75 \][/tex]
[tex]\[ \text{Property Damage} = \$ 120.50 \][/tex]
[tex]\[ \text{Collision} = \$ 275.75 \][/tex]
[tex]\[ \text{Comprehensive} = \$ 100.00 \][/tex]

Add these amounts together for the total original annual premium:

[tex]\[ \text{Total Original Annual Premium} = \[tex]$ 31.75 + \$[/tex] 120.50 + \[tex]$ 275.75 + \$[/tex] 100.00 = \$ 528.00
\][/tex]

2. Calculate the Discount Amount:
Cindy is offered a discount of 4.5%. To find the amount of the discount, multiply the total original annual premium by the discount rate:

[tex]\[ \text{Discount Rate} = \frac{4.5}{100} = 0.045 \][/tex]

Calculate the discount amount:

[tex]\[ \text{Discount Amount} = \[tex]$ 528.00 \times 0.045 = \$[/tex] 23.76
\][/tex]

3. Calculate the New Annual Premium:
To find the new annual premium after applying the discount, subtract the discount amount from the total original annual premium:

[tex]\[ \text{New Annual Premium} = \[tex]$ 528.00 - \$[/tex] 23.76 = \$ 504.24
\][/tex]

Thus, Cindy's new annual premium, including the discount, is:

[tex]\[ \boxed{\$ 504.24} \][/tex]

The correct answer is:

a. \$ 504.24
