Answer:
Let l represents the number of lilies and r represents the number of roses.
As per the statement: Flannery used 30 lilies and 78 roses to create six identical flower arrangements.
Total number of flowers = 30 + 78 = 108
Number of flower arrangement needed is, 6
i.e, l = r = 6
Number of Lilies in one arrangement =[tex]\frac{30}{6} =5[/tex]
Number of Roses in one arrangement =[tex]\frac{78}{6} =13[/tex]
then;
[tex]5l+13r =108[/tex]
Therefore, an equation to describe the relationship between l and r are:
[tex]l =r[/tex]
[tex]5l+13r =108[/tex]
Answer:
Number of roses = number of roses per lily x number of lilies
r=13/5 l
