Given that T=kx/y,find the percentage increase in T when k, x and y all increase by 20%

OpenStudy (anonymous):

k->1.2k .. etc can you do it now ?

OpenStudy (anonymous):

the answer is 0 i suppose ............. as T is directly proportional to x/y and x, y, both change as x+20x,y+20y so the variable T does not increase

OpenStudy (anonymous):

but you got k there as well..

OpenStudy (anonymous):

oh sorry please dont mind iam really sorry for that its 20%

OpenStudy (anonymous):

yes.. that's right
