ANSWER:
At the end of 24 months we will receive $2566.135 as the interest earned on $2300 is $266.135.
SOLUTION:
Given, I graduated from high school and received $1500 in gifts from family and friends. You also received scholarships in the amount of $800.
Total amount received into a 24-month CD at 5.5% compounded daily.
We have to find how much will you receive at the end of 24 months.
Now, amount that is compounded daily is given by:
→ (1)
where A is final amount and a is deposited amount
r is interest rate.
n is number of days
t is number of years
now, a = 1500 + 800 = 2300, r = 5.5%, n = 365 days per year, t =
= 2 years.
Substitute above values in (1)
![\mathrm{A}=2300 *\left(1+((5.5)/(100))/(365)\right)^(365 * 2)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/9owvkc98lrck4pcolrhv22uxrqkceo8deb.png)
![\begin{array}{l}{A=2300(1+0.000150)^(730)=2300(1.00015)^(70)} \\ {=2300 * 1.11571=2566.1350}\end{array}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/wa4oo483krvyxytv3rwhmjybo6aemmq8v3.png)
So, in the end we will receive an amount of $2566.135.
Now, interest earned = received amount – deposited amount = 2566.135 – 2300 = $266.135
Hence, at the end of 24 months we will receive $2566.135 as the interest earned on $2300 is $266.135.
