You are selling a coin to a customer for $120.
However, your customer wants 15% discount. After haggling for an hour and nearly killing him, you decided to give him a 12% discount. But... he also has a trade in a coin, which he bought from you for $80 some time ago. However, you allow him 75% of his purchase price of that coin towards the purchase of the new coin.
What does your customer still have to pay you to get the new coin?

120x.12=14.4
120-14.4=105.6
80x.75=60
105.6-60=$45.60

Agreed selling price of new coin to be bought base on 12%:
120 - 120*(.12) = 105.6 dollars
Money derived from trade in of old coin by the buyer:
75% of 80.00 = .75 * (80) = 60.00
The customer would have to pay:
105.6 - 60.00 = 45.6 dollars

$45.60.
12% of $120= $14.40.
75% of $80 is $60.
$14.40 + $60 = $74.40
$120 - $74.40 = $45.60
