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?
Think hard. Detailed solution:
80
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.

.

Thus, the answer is 80
