Let's figure this out! Okay, so the original price is 24. 45% is taken off. Well, we just multiply 24 and 0.45! (45% = 45/100 = 0.45) When we do that, we get 10.8. Now, a common mistake is to just say 10.8 is the answer. Unfortunately for Charlie, that is only how much is being taken off. If 10.8 is being taken off 24, we subtract. 24 - 10.8 = 13.2. And there we have it!
Charlie payed $13.2.
Hope this helps!
Answer:

Answer:
g(x + 8) = 10x + 105 wherever you see it among your answers.
Step-by-step explanation:
I think I have enough here that I can answer the question, but you should always put in your givens.
f(x) = 10x + 25 Put g(x) where you see x in f(x)
f(g(x)) = 10(g(x) + 25 Put the value for g(x) where you see g(x)
f(x+8) = 10(x + 8) + 25 This might be the answer
From here it is a guess.
f(x+8) = 10x + 80 + 25 Combine the like terms
f(x+8) = 10x + 105
Answer:
-4
Step-by-step explanation:
4x+3y=-1
3x + y=-7
Solve for Y
3x+y=-7
-3x. -3x
y= -3x - 7
Plug in Y into the top equation
4x + 3 (-3x - 7) = -1
Distribute the Parenthesis
4x -9x-21=-1
Combine Like terms
-5x = 20
Divide by -5 on both sides
20/-5
x = -4
