Sarah wants to deposit $2,125 into savings accounts at three different banks: Bank of the US, 7/4 Bank, and Catch Bank. She will deposit four times as much into Catch Bank as 7/4 Bank because they offer a higher interest rate. She also expects the Bank of the US deposit to be 25% of the total of the other two deposits. How much will Sheila deposit into the Bank of the US savings account?

Question

konradzuse · Answer

I'm not sure 100% how to do this, but we need to look at it in this way.

X is the amount we want to find for 7/4 bank.

7/4 bank = x
Catch = 4x
US Bank is 0.25(25%) of the TOTAL of the others.  So I would say 0.25(5x)

konradzuse · Answer

So it seems like we are looking at x + 4x + (0.25(5x)) = 2125?

As I said above.

X is the amount we want to find for 7/4 bank.

7/4 bank = x
Catch = 4x
US Bank is 0.25(25%) of the TOTAL of the others.  So I would say 0.25(5x)

There are 3 banks...

We found x to be 340 so that's 7/4 bank, now what is 4x, and 0.25(5x) = 425 yes.

anonymous · Answer
