Tommy, who was $32$ years old, deposited $$1000$ at the end of each month into a tax$-$free retirement account that earned interest at a rate of $3\%$ per year compounded monthly. On the other hand, his twin brother Victor decided to open a tax$-$free retirement account $10$ years after Tommy opened his. If Victor's account earns interest at the same rate as Tommy's, what is the monthly deposit amount that Victor should make into his account so that both brothers will have equal amounts of money in their accounts when they reach the age of $75?$
