The granola summer buys used to cost $6.00 per pound, but it has been marked up %15.=> 6 dollar per pound is the price of the granola summer.=> now the current price has been marked up to 15%.Let's solve for the price.=> 15% = 15% / 100% = .15=> 6 dollars * .15 = 0.9Now, let's add=> 6 + 0.9 = 6.9 is now the price of the granola summer.

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.
