<human>:  Mr. Roberts can buy a television for $400 cash or $120 down payment and $30 a month for 12 months. How much can he save by paying cash?
<bot>: How much will Mr. Roberts pay in total? ** Mr. Roberts will make a total payment of $30 x 12 = $<<30*12=360>>360 for 12 months.
How much does the television cost when not paid in cash? ** Thus, the television costs $360 + $120 = $<<360+120=480>>480 when not paid in cash.
How much can he save by paying cash? ** Therefore, Mr. Roberts can save $480 - $400 = $<<480-400=80>>80 by paying cash.
