Adining room table and chairs are priced at $869. mrs. brown has a coupon for $75 off the original price. if the tax on the sale amount is 8%, how much will mrs. brown pay for the table and chairs?

869 * .08 = 69.52
69.52 + 869 = 938.52
938.52- 75 =  863.52

$869 is the original price...
She has a $75 off coupon
Tax is 8% on sale amount

1) So, first, you will take your original price (869) and subtract $75.

869 - 75 = $794

2) You know that there is now a tax on the $794

8% is the same as 0.08. Now, you will multiply $794 x 0.08 to give you your final price. 

794 x 0.08 = $63.52

Hope this helped : ) 

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.
