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. $9,138.44
b. $10,000.00
c. $14,247.00
d. $9,141.44

Cost of the basic car bought by John Gray = $8250
Optional cost incurred after buying = $324
Total cost before tax = 8250 + 324
                                 = $8574 
Percentage of sales tax incurred = 6%
Amount of sales tax charged = (6/100) * 8574
                                               = $514.44
License and registration fees paid = $50
John's total cost = 8250 + 324 + 514.44 + 50
                          = 9138.44 dollars
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the first option or option "A".

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

answer: the function g(x) has the greatest slope.
