9. Barbara bought some lilies that were $3 each and roses that were $4 each. She bought
a total of 16 flowers for $54.
How many lilies did Barbara buy?

Respuesta :

Answer:

10 lilies

Step-by-step explanation:

As we know, lilies are $3 and roses are $4,

Lets substitute

R=Roses

L=Lilies

R+L=16

3L+4R (3 and 4 for Prices)

16-L=R right?

Sooo....

3L+64-4L=54

Simplify

-L=-10

L=10, giving you the answer
