So your friend bought 1 set of brush and 5 bottles of paint
you bought 2 brushes and 7 bottles of paint
1 bottle=3.69
friends cost+your cost=51.69
total you bought 3 brushes and 12 bottles
each bottle is 3.69
12*3.69=44.28
totalcost=51.69=3brushes+12bottles
51.69=3brushes+44.28
minus 44.28 from both sides
7.41=3brushes
divide both sides by 3
2.47=1brush
1 set of paint brushes=$2.47
16.6 with a line on top of 6. When you divide 50 by 3 you get 16.6 a repeating decimal.you would round and get 17. I think it's correct!!

Step-by-step explanation:
f(g(2)) means "put 2 into g(x) and then take that answer and put it into f(x)"
Given:

and

Now, let's find g(2) first:
g(x) = x - 1
g(2) = 2 - 1
g(2) = 1
Now, lets put this into f(x). So we have:

That is f(g(2)) = 4
