4⋅f(6)−6⋅g(5) khan academy

I was confused on if you meant to put an = instead of - so I solved for both ways.

4 x f(6) - 6 x g(5)

4 x 6 = 24, then 24f

6 x 5 = 30, then 30g

Simpiler equation:

24f - 30g

4 x f(6) = 6 x g(5)

24f = 30g

24(5) = 30(4)

120 = 120

10% is 8, so multiply this by 7 to get 70%.

That would 56.

To get the 2% think of what 1% is then double it.

1% would be 0.8, so 2% would be 1.6

Then, to get the 0.5% just cut what 1% of it is.

Since 1% would be 0.8, you cut it in half to get 0.4.

Combine the 56, 1.6, and 0.4.

1.6+0.4=2.

So the problem would read 56+2=58.

58 is 72.5% of 80 games.
