John gray bought a basic car for $8,250.00, with options that cost $324.00. there's a 6% sales tax in
his state and a combined $50.00 license and registration fee. what was john's total cost?
a. $9,141.44
b. $14,247.00
c. $9,138.44
d. $10,000.00

Cost of basic car = $8250
Optional cost = $324
Total cost of basic car and optional items for John= (8250 + 324) dollars
                                                                  = 8574 dollars
Then
Percentage of sales tax = 6%
Amount of sales tax = 8574 * (6/100) dollars
               = 514.44 dollars
License and registration fee combined = $50
Then total cost of John in regards to buying the car = 8574 + 514.44 + 50
                                                                                    = 9138.44 dollars
So option "C" is the correct option in regards to the question given.
