The total discount of a pair of shoes is $200 x 30/100 = $<<200*30/100=60>>60.

He spent $200 - $60 = $<<200-60=140>>140 for a pair of shoes.

The total cost of two shirts is $80 x 2 = $<<80*2=160>>160.

The initial cost of his purchase is $140 + $160 = $<<140+160=300>>300.

He got an additional $300 x 5/100 = $<<300*5/100=15>>15 discount upon checkout.

Therefore, Erwan spent $300 - 15 = $<<300-15=285>>285 after all the discounts.

Erwan went on shopping. He purchased a pair of shoes at $200 but discounted 30%, and two shirts at $80 each. Upon checkout, the cashier said that there is an additional 5% discount. How much did he spend after all the discounts?
