Kenneth signed up to receive Internet service for $13 per month plus a $30 start-up fee. How many months can he receive Internet service for $134?
Let m be the number of months
$30+$13m= $134
13m= 134-30
= 104
m=8
$30+$13m=$134
-30 -30
13m=134
/13 /13
m=10.3
about 10 months
13M + 30 = 134 subtract 30 from both sides
13M = 104 divide both sides by 13
M = 8 months
