Answer:

Let's solve for f.

x=5+4(x−4)f(7)

Step 1: Flip the equation.

28fx−112f+5=x

Step 2: Add -5 to both sides.

28fx−112f+5+−5=x+−5

28fx−112f=x−5

Step 3: Factor out variable f.

f(28x−112)=x−5

Step 4: Divide both sides by 28x-112.

f(28x−112)28x−112=x−528x−112

f=x−528x−112

Answer:

f=x−528x−112

Answer:If shoes are for all games in row,  P = 2 + 3 g   If not,  P = 5 g  ,with g the number of games

g g a m e s , so  P ( g ) = 2 + 3 g   Else, you have to pay  g s h o e s  and  g b o w l p a r t y ,so  

P ( g ) = 2g + 3 g⇔ P ( g ) = 5 g
