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? Let's answer step by step:
The total discount of a pair of shoes is $200 x 30 / 100 = $60. He spent $200 - $60 = $140 for a pair of shoes. The total cost of two shirts is $80 x 2 = $160. The initial cost of his purchase is $140 + $160 = $300. He got an additional $300 x 5 / 100 = $15 discount upon checkout. Therefore, Erwan spent $300 - 15 = $285 after all the discounts. The answer: 285.
