When you roast the coffee, it loses 12% of its weight. how much fresh coffee do you need in order to get 14 225 lb. of roasted coffee?

Let be the weight of the fresh coffee, and be the weight of the roasted coffee. The equation described by the first sentence is

In this case, we know and want to solve for : the equation becomes

To solve for , multiply both sides by 25/22:

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

60 + 3

63

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
