 <translate> The question Bill is trying to control the pests in his garden. Each spider he introduces eats 7 bugs, and each time he sprays the garden he reduces the total bug population to 80% of what it was previously. If the garden has 400 bugs to start, and Bill sprays once and introduces 12 spiders, how many bugs are left? <yor> Ìbéèrè náà ni pé Bill ń gbìyànjú láti kápá àwọn kòkòrò inú ọgbà rẹ̀.
