Pattern and Functions
Work in groups. Consider the original problem again. That is, you deposit $1,000 for 18 y in a bank that pays interest at a rate of $,05 for every dollar in account each year.
Without calculating, predict which of these changes would increase the final amount the most.
-doubling the starting amount from $1,000 to $2,0000
-doubling the rate the bank pays to $.10 for every dollar in the account eacr year
-doubling the time from 18 y to 36 y
