Emma is saving money for college. She has $800 and wants to deposit it into 2 different savings accounts. She decides to deposit $500.00 into an account, Account I, which earns 2.5% annual simple interest. She will then deposit $300 into an account, Account II, which earns 2 1/4% interest compounded annually.

If Emma makes no other deposits or withdrawals, what is the total amount of money she will have at the end of 3 years?
Note, show your answer and all steps needed to complete.

i seriously need help the question is due soon. :,)

2 years later still no help, bum

just use your interest formulas. Her balance will be

500(1 + 0.025*3) + 300(1 + 0.225)^3

Hi! I am very bad at this. I see your answer but is there anyway you can explain how you got that?

Use interest formulas, as oobleck said.

To find the total amount of money Emma will have at the end of 3 years, we need to calculate the amount of interest earned from each account and add it to the initial deposit.

Let's start with Account I, which earns 2.5% annual simple interest. Simple interest is calculated using the formula:

Interest = Principal (initial deposit) * Rate * Time

For Account I:
Principal = $500.00
Rate = 2.5% = 0.025 (in decimal form)
Time = 3 years

Interest (Account I) = $500.00 * 0.025 * 3 = $37.50

Now let's move on to Account II, which earns 2 1/4% interest compounded annually. Compound interest is calculated using the formula:

A = P (1 + r/n)^(n*t)

Where:
A = Final amount
P = Principal (initial deposit)
r = Annual interest rate (in decimal form)
n = Number of times interest is compounded per year
t = Number of years

For Account II:
Principal = $300.00
Rate = 2 1/4% = 2.25% = 0.0225 (in decimal form)
Compounding frequency = annually
Time = 3 years

A (Account II) = $300 * (1 + 0.0225/1)^(1*3) = $300 * 1.0225^3 ≈ $300 * 1.06818 ≈ $320.45

Now, we can calculate the total amount Emma will have:

Total amount = Initial deposit + Interest Account I + Amount Account II
= $800 + $37.50 + $320.45
= $1157.95

Therefore, Emma will have approximately $1157.95 at the end of 3 years if she makes no other deposits or withdrawals.

Remember to double-check all the calculations to ensure accuracy.
