assistant
How many red roses does Mrs. Amaro have? ** Mrs. Amaro has 80 x 3/4 = <<80*3/4=60>>60 red roses.
How many roses are not red? ** So, 80 - 60 = <<80-60=20>>20 roses are not red.
How many yellow roses are there? ** Then, 20 x 1/4 = 5 of those 20 non-red roses are yellow.
How many white roses are there? ** Hence, 20 - 5 = <<20-5=15>>15 roses are white.
How many of Mrses. Amaro's roses are either red or white? ** Therefore, 60 + 15 = <<60+15=75>>75 roses are either red or white.
