She needs twice as many lilies as the 3 snapdragons in the arrangement so she needs 2*3 = <<2*3=6>>6 lilies

She needs 8 roses, 12 daisies, 3 snapdragons and 6 lilies for a total of 8+12+3+6 = <<8+12+3+6=29>>29 flowers per arrangement

She needs 29 flowers per each of the 10 tables for a total of 29*10 = <<29*10=290>>290 flowers
