# Butterfly Flowers

##### Stage: 1 Challenge Level:

We had correct solutions to this problem from Rebeccawho goes to Lexden Primary School, and also from Jake, Sam, Rebecca, Ryo, Luke, Katie and Charlie from Moorfields Junior School. Ryo and Luke explain how they arrived at the answer:

We used $10$ and $5$ for $15$, $10$ and $6$ for $16$, $10$ and $2$ for $12$, $10$ and $9$ for $19$, $10$ and $4$ for $14$, $10$ and $1$ for $11$, $10$ and $7$ for $17$ so we did not use $10$ and $3$.

Rebecca from Lexden Primary goes on to say:

The flower number $18$ has no butterflies. It needs a $10$ and a $8$.
