PLEASE HELP ASAP HELP A GIRL OUT <3 When their child was born, her parents invested $40,000 in a plan guaranteed to increase by 3% per year. The logarithmic
function y = 77.9 log x/40,000
can be used to determine the number of years, y, it takes for the investment to be worth x
dollars. After how many years will the investment be worth approximately 100% more than it was originally and how old will their child be when the investment is worth about $400,000
