Can you explain how to solve this math problem: Davos bought 2 shirts from the mall that cost $30 each. If he bought them with a 40% discount, how much did Davos pay for the 2 shirts?
The total price of the 2 shirts is $30 x 2 = $60.
The total discount on the 2 shirts is $60 x 0.40 = $24.
Therefore, the total amount Davos paid for the 2 shirts is $60 - $24 = $36.
