Decimal P6 2009 SA2 P2 MGS Q11

11. The table below shows the charges incurred when making overseas phone call.

Miss Ong made an overseas phone call which lasted 25 ½ min. How much must she pay for the overseas phone call?


25 ½ - 5 = 20 ½

First 5 min -- > $8.00
Balance 20 ½ min -- > 21 x 0.15 = $3.15

3.15 + 8.00 = $11.15


She must pay $11.15 for the overseas phone call.
