John buys a new set of golf clubs for $757.75, including tax. If the sales tax rate is 8.25%, then what is the cost of the set of golf clubs? How much did he pay in tax?

Total cost: $820.26      Paid in tax: $62.51

Step-by-step explanation:

First you have to get the Tax. Since the Tax is 8.25% MOVE the decimal 2 spots to the right so now it is 0.0825.

Multiply 0.0825 by 757.75 you will get 62.514375.

Dont get scared of the big number simply simplify and you get the tax.

if you want the total he paid add tax and original cost.

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

1/800 is the right answer
