Gien made 16 muffins and 1/4 of them had nuts, so 16 x 1/4 = 4
Gien made 4 muffins with nuts
Catrina made 1 less muffin than Gien, so 16-1=15, so Catrina made 15 muffins. 1/3 of them had nuts, so 15 x 1/3 = 5
Catrina made 5 muffins with nuts
Lisa and Meg both made 3 more muffins than Catrina, so 15+3=18
Lisa and Meg made 18 muffins each
Lisa made 1/3 of her muffins with nuts, so 18 x 1/3 = 6
Lisa made 6 muffins with nuts
Meg made 1/2 of her muffins with nuts, so 18 x 1/2 = 9
Meg made 9 muffins with nuts
They don't say how many muffins Wayne made so we have to use information from the beginning. There were 87 muffins total so we need to add up the total number of muffins made by the other kids (16+15+18+18=67) and then subtract that from 87 (87-67=20)
Wayne made 20 muffins
Wayne made 1/4 of her muffins with nuts, so 20 x 1/4 = 5
Wayne made 5 muffins with nuts
So, now you just need to add up all of the muffins made with nuts
4+5+6+9+5=29
29 of the muffins had nuts
