solve for r 13,962= 16024(1-r)^4

Nnesha (nnesha):

first divide both side by 16024

OpenStudy (anonymous):

Ok, so would I leave it as a fraction?

OpenStudy (anonymous):

13,962/16,024?

OpenStudy (anonymous):

yeah then take the fourth root

Nnesha (nnesha):

you can but decimal is better than fraction up to you!

OpenStudy (anonymous):

you have to use a calculator anyway to do this boring problem, might as well do it in one step http://www.wolframalpha.com/input/?i=13%2C962%3D+16024%281-x%29^4 click on "approximate form" to get a decimal

OpenStudy (anonymous):

so it would be .8713^4?

OpenStudy (anonymous):

I got .4237 as my answer

Nnesha (nnesha):

nope that is not right
