<span>4.8 (x+4)=2.6
Use distributive property
4.8x + 19.2= 2.6
Subtract 19.2 from both sides
4.8x = -16.6
Divide 4.8 on both sides so that the only thing remaining on the left side is the variable x.

substitute for x=2
f(2)=3.45*2+12-------> f(2)=$18.90/month
$18.90 is the amount, that </span><span>Catherine pays for 2 units of power in 1 month
