with c= cost and p= # premium channels
a.) Excel company : c= $32+$8p
Best Cable: c= $26 + $10p
b.) set your equations equal to each other
$32+$8p = $26 + $10p
Solve the equation
get the p values on the same side and the lone values on the same side
$32-$26 = 10p-8p
$6 = 2p
Divide by 2
P= 3
So the answer to b is 3
c.) just plug 2 into each of your equations
c=$32+$8(2) $48
c=$26+$10(2) $46
So you would want to subscribe to the Best Cable company to spend less money
Just multiply the solutions you got by twelve then subtract the two
$48(12)= $576
$46(12)= $552
So the Hortons would save $24 in one year
