Let's break down the information given:
- Lila has \( c \) cups of juice.
- Miren has times the number of cups of juice as Lila. This means Miren has \( k \times c \) cups of juice, where \( k \) is the multiplier indicating how many times Miren has more than Lila.
- Helena has \( m \) of a cup of juice less than Miren. This means Helena has \( k \times c - m \).
Based on this information, we can create the expression for the number of cups of juice Helena has:
Expression for Helena's juice: \[ k \cdot c - m \]
To summarize, if you have the defined operations and variables:
- \( c \): Lila's cups of juice
- \( k \): Multiplier for Miren's cups relative to Lila's
- \( m \): Amount less than Miren that Helena has
The final expression for the number of cups of juice Helena has is \( k \cdot c - m \).
