write and solve an equation how many minutes were used in a month if the monthly bill is $16.99

A long-distance phone company charges $ 4.99 per month plus 10 cent per minute.

monthly bill=$4.99+[($0.10)x]
x=quantity of minutes
$16.99=$4.99+[($0.10)x]
$12.00=($0.10)x
The units of $ on both sides cancels...
12.00=0.10x
120=x
120 minutes
