Question

Solve this equation for C

R=5(C/A-0.3)

Answer 1

isolate the variable by dividing each side by factors that don't contain the variable c=ar/5+0.3a

Answer 2

Answer:

$C=0.2RA+0.3A$

Step-by-step explanation:

To solve the equation $R=5(\frac{C}{A}-0.3)$ for $C$ you must:

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

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

$\mathrm{Simplify}\\\\\frac{C}{A}-0.3=\frac{R}{5}$

$\mathrm{Add\:}0.3\mathrm{\:to\:both\:sides}\\\\\frac{C}{A}-0.3+0.3=\frac{R}{5}+0.3$

$\mathrm{Simplify}\\\\\frac{C}{A}=0.2R+0.3$

$\mathrm{Multiply\:both\:sides\:by\:}A\\\\\frac{CA}{A}=0.2RA+0.3A$

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