# Math Help - Finance

1. ## Finance

Hi,

I need help with my HW. I've done the ans but wanted to check if they're correct:

Find the future value of $800 to be received weekly for 13 weeks from today if the interest rate is 18 percent compounded weekly? This is how i solved it: S=A*(1+i)^n S=800*(1+0.018/4)^13*4 any idea? Thanks! 2. ## Re: Finance Also this one: How much money will you have when you can withdraw it on your 16th birthday, if an investment was made on your behalf equal to 11x your age from 10 to 14 with 17% interest? Future Value: S=A*(1+i)^n 100(1+0.017/?)^?*? I don't know what goes under ? Thanks 3. ## Re: Finance If you deposit ten dollars everyday for two weeks earning 25.40% compounded daily, how much will you have at the end? This is how i solved it: Two Week: 1 2 3 4 5 6 7(week1) 8 9 10 11 12 13 14(week2) FV: S=A*(1+i)^n 10*(1+0.2540/14)2*14 I dont know if above it correct. I raised it to 2 because of 2 weeks and 14 is for compunded daily since there are 14 days in two weeks. 4. ## Re: Finance Find the future value at the end of 6years of$1881 invested today and on each anniversary at an interest rate of 4% compounded annually:
FV: S=A*(1+i)^n
1881(1+0.04/1)^6*1

Rasied to 6 due to six years period and i don't know how i would translate "on each anniversary" but i put 1 for annually compound.

5. ## Re: Finance

Find the present value of the following semiannual cash flow stream if the interest rate is 8.8% compounded semiannually: 1 = $100, 2 =$300, 3 = $500, 4 =$200, 5 = $100, 6 =$500, 7 = \$400

A=S/(1+i)^n
First: 100/(1+0.088/1)^2*1

Second: 300/(1+0.088/2)^2*2

Third: 500/(1+0.88/3)^2*3

Fourth: 200/(1+0.88/4)^2*4

Fifth:

Sixth:

Seventh:
