To find the predicted total receipts for world tourism for the decade from 2003 to 2013, we need to substitute 18 for t in the given function. 
11ea984b_b06e_29be_9029_033eba96b402_TB4005_11 = 345.4e^(0.069t)
11ea984b_b06e_29be_9029_033eba96b402_TB4005_11 = 345.4e^(0.069*18) 
11ea984b_b06e_29be_9029_033eba96b402_TB4005_11 ≈ $5,279.3 billion (rounded to one decimal place)

Therefore, the answer is C.
