Answer:
1. c. $450.
2. 22%
Step-by-step explanation:
1. We will use simple interest formula to find the amount of interest after 2 years on $5,000. As interest is not compounded, so it will not matter if she moves the simple interest earned in separate account or not.
, where,
I= Amount of interest.
P= Principal amount.
r= Interest rate in decimal form.
t= Time in years.

Upon substituting our given values in above formula we will get,


Therefore, Tracy will get an amount of $450 as simple interest after 2 years and option c is the correct choice.
2. Sylvia bought a 6-month $1900 certificate of deposit. At the end of 6 months, she received a $209 simple interest.
6 months is same as 1/2 year.
