Nancy bought a mobile phone marked at $720 at a discount
of 20% and she had to pay 5% tax. If Nancy had to put 20% of
what she had to pay including tax as a deposit, how much
money did she have to pay for the deposit?

20% of $720( original cost)= $144 (discount)
$720- $ 144 = $576 (discounted cost)
5% tax = $36 (tax payed)
tax + cost of phone = $612 (total of both tax and discounted cost)

20% of $612=$122.40 (deposit cost?)
