When he added 7 more trays, the total number of trays became 8 trays + 7 trays = 15 trays. Since each tray contains 36 eggs, the total number of eggs to be sold is 36 eggs / tray * 15 trays = 540 eggs.
Therefore, the answer is 540. <ibo> Mgbe Heman chịkọtara efere iri ma tụfuo abụọ, ọ bụ efere iri fọdụrụ ya - efere abụọ hà efere asatọ. Mgbe ọ gbakwunyere efere 7 ọzọ, ngụkọta nke efere ndị ahụ ghọrọ efere 8 + efere 7 = efere 15. Ebe ọ bụ na otu tray nwere àkwá 36, ngụkọta nke àkwá a ga-ere bụ àkwá 36 / tray * 15 trays = àkwá 540. N'ihi ya, azịza ya bụ 540.
