Jessica has a basic cable television service for $15 per month. If she adds the movie channels, it will cost an additional $12 per month. The sports channels cost $3 less per month than the movie channels. If Jessica adds the movie channels and the sports channels, what will her total monthly payment be?
The sports channels cost $12 - $3 = $<<12-3=9>>9 per month.
Jessica has to pay $15 + $12 + $9 = $<<15+12+9=36>>36 in total per month.
