Price formula doesn’t work as it should

Good morning, I created a price formula (adding the shipping cost before the formula) of 65%, it works on some products, but on others it applies wrong.
example: In the product “RORONOA ZORO – ONE PEICE – BANDAI / BANPRESTO”

It costs: $ 25.80

Shipping: $ 9.44

Total amount: $ 35.24

Price that should be in the store with application of the formula: $ 58.15 x 5.53 (Value of the currency of my country R $) = R $ 321.56

Amount left: R $ 287.67
