Question

The regular cost of the car is c and there is 7.75% sales tax. What is the cost of the car including tax?

Answer 1

To find the expense of the vehicle including charge, you can utilize the equation:

\[ \text{Total cost} = \text{Cost of the car} + (\text{Sales charge rate} \times \text{Cost of the car}) \]

For this situation, the deals charge rate is 7.75%, which can be communicated as a decimal by partitioning by 100 (i.e., 0.0775).

In this way, the equation becomes:

\[ \text{Total cost} = c + (0.0775 \times c) \]

Improve on the articulation to get the all out cost of the vehicle, including charge.
