McGee won a cat competition that had given him the 1st place reward of 400.00 dollars. Mr. Orso took McGee to the bank to get McGee an account with a 10% continuously compounded interest rate when depositing the 400 dollars. How much money will McGee have after 1 year of that investment? (Round to the nearest dollar)

• $450

• $109

• $442

• $115
