Answer:


C=0.2RA+0.3A

Explanation:

To solve the equation
R=5((C)/(A)-0.3) for
C you must:


\mathrm{Switch\:sides}\\\\5\left((C)/(A)-0.3\right)=R


\mathrm{Divide\:both\:sides\:by\:}5\\\\(5\left((C)/(A)-0.3\right))/(5)=(R)/(5)


\mathrm{Simplify}\\\\(C)/(A)-0.3=(R)/(5)


\mathrm{Add\:}0.3\mathrm{\:to\:both\:sides}\\\\(C)/(A)-0.3+0.3=(R)/(5)+0.3


\mathrm{Simplify}\\\\(C)/(A)=0.2R+0.3


\mathrm{Multiply\:both\:sides\:by\:}A\\\\(CA)/(A)=0.2RA+0.3A


\mathrm{Simplify}\\\\C=0.2RA+0.3A
