Refer back to question #10. If Lili had invested her money in a CD in the 1980's (when CDs had the highest rates in modern history) she could have received an interest rate of 11% How much money would Lili have earned in total in the 1980 s? Answer: __ Blank 1: square

To calculate the total amount of money Lili would have earned in the 1980s, we need to know the initial amount of money she invested in the CD.<br /><br />Let's assume that Lili invested $P$ dollars in the CD in the 1980s.<br /><br />The interest rate for the CD in the 1980s was 11%, which means that for every $100 she invested, she would have earned $11 in interest.<br /><br />To calculate the total amount of money Lili would have earned, we need to multiply the initial amount of money she invested by the interest rate.<br /><br />The formula for calculating the total amount of money earned is:<br /><br />Total amount = Initial amount * Interest rate<br /><br />In this case, the initial amount is $P$ and the interest rate is 11% or 0.11.<br /><br />So, the total amount of money Lili would have earned is:<br /><br />Total amount = $P * 0.11<br /><br />Therefore, the answer to the question is:<br /><br />Blank 1: $P * 0.11$
