Cost of mobile phone = ` 7 6 5 0 . 5 0
Money Sanya has = – ` 6 4 7 5 . 0 0

Money needed = ` 1 1 7 5 . 5 0

Thus, Sanya needs `1175.50 more to buy the mobile phone.

Get it right!

Subtract `6475 from `7650.50:

` 7 6 5 0 . 5 0 ` 7 6 5 0 . 5 0
– ` 6 4 . 7 5 – ` 6 4 7 5 . 0 0

` 7 5 8 5 . 7 5 ` 1 1 7 5 . 5 0
