(Will give brainiest if you answer) I invested all of my money in an investment that pays the same annually compounded interest rate for 30 years. At the end of the first 10 years, my investment had doubled in value.
a. After how many years will my original investment have multiplied by 4 in value?
b. If I initially invest 5,000 dollars, how much will my investment be worth at the end of 30 years?
