Mia invests $2,000 in a money market account that earns 6% annual interest, compounded continuously. Approximately how many years will it take her money to grow to the $4,500 she needs for her small business start-up

If you would like to simplify a - {4b - [a - (5b - c) + 3c - (a - b - 9c)]}, you can do this using the following steps:

a - {4b - [a - (5b - c) + 3c - (a - b - 9c)]} = a - {4b - [a - 5b + c + 3c - a + b + 9c]} = a - {4b - [- 4b + 13c]} = a - {4b + 4b - 13c} = a - {8b - 13c} = a - 8b + 13c

The correct result would be b) a - 8b + 13c.
