This is an exponential growth problem.

The growth rate is 4% (0.04).

The time is 10 years (10 years from 2005 to 2015)

A = P (1+i) t

A = amount spent in 2015

P = amount spent in 2005

i = interest rate expressed as a decimal

t = # years

A = 500 (1.04) 10

A = 500 (1.480244)

A = 740.122 = => 740 billion
