Answer the following question.
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?
Step-by-step reasoning process: Mr. Roberts will make a total payment of $30 x 12 = $360 for 12 months. Thus, the television costs $360 + $120 = $480 when not paid in cash. Therefore, Mr. Roberts can save $480 - $400 = $80 by paying cash.
The answer is 80.
