Let x = last years spending
this years spending was 5 billion more, or x + 5
this years spending was equal to last years plus 22% of last years
(1.22)x = x + 5
x + .22x = x + 5
subtract x from both sides
.22x = 5
this equation could be your starting point also. It says 5b is 22% of last years spending
x = 5/.22
x = 22.72
you want this years speninding, which is x + 5
x + 5 = 27.72 billion
