Evaluate whatever rsolve returns. Recurrence relations

savecancel

sage: from sympy import *
sage: x = Function('x') 
sage: n = var('n')
sage: q = rsolve(x(n+1)-(1+(3/(100)))*x(n),x(n),{x(0):10000})
sage: q
10000*(103/100)**n

I want to evaluate the result , say q(5) , but i get the following: ''TypeError: 'Mul' object is not callable''. Can someone help me
