Answer:

3636

Step-by-step explanation:

2015 - 2009 = 6

3.2 x 6 = 19.2

19.2/100 x 4500 = 864

4500 - 864 = 3636

Answer:

  16

Step-by-step explanation:

Put the numbers where the variables are and evaluate:

  G(4) = 2(4) -1 = 7

  H(5) = 5

Then the desired sum is ...

  F(3) +G(4) -2H(5) = 19 +7 -2(5) = 16
