Mr.Mcleinis went to the fair and got some food he ordered 5 cakes (f) , 6 tacos(t),and 3 Lemonade's (d)
Mrs.williumms also went to the fair and ordered 3 cakes (f) ,1 turkey leg (L) ,and 2 Lemonade's (d)
assuming this is addition you have to add 5,6 and 3 that will get you 14 and then you will have to add 3,1 and 2 witch will get you 6 if you add 14 and 6 you will get 20. ps: i hope this helps
