maths question

[Ilikeitblackplease]

1000= (47.5/1.0448)+(47.5/1.0966)+(1047.5/(1+y)^3)

I keep getting 1.1495 for (1+y)^3 but it should be 1.1534
my step
1000-45.46-43.31=(1047.5/(1+y)^3)
911.23=1047.5/(1+y)^3

911.23 (1+y)^3=1047.5
(1+y)^3=1047.5/911.23
(1+y)^3=1.1495
(1+y)=1.1495^1/3
(1+y)=1.047

but answer is (1+y)^3=1.1534

BASE IS UNDEFENDED!

You forgot to multiply the definition of the root cause, which normally gives the ... wait what.

Have you tried working out this maths question in your...

Boxing stance?

Sure you copied the question right?

Everything checks out, perhaps the answer is wrong, misprints are not uncommon

For equation

1000= (47.5/1.0448)+(47.5/1.0966)+(1047.5/(1+y)^3)

the answer is

(1+y)^3=1.1495

I'd guess at rounding approximations from earlier parts of the question.

 

[Nerusy]

nvm

hmm

r2 isn't exactly correct given the input, so I would say that it's down to rounding.
