The regular price of a refrigerator was $400. During a clearance sale, Mr. Terry bought it at a discount of 20%. In addition, he had to pay 5% tax. If Mr. Terry had to put 10% of what he had to pay including tax as down payment, how much money did he have to pay for the down payment?

$

The selling price of the refrigerator: 400 × (100% – 20%) = 320

The total payment with tax: 320 × (100% + 5%) = 336

Thus, The down payment: 336 × 10% = 33.60
