To express the revenue from selling hot chocolate and apple cider using the variables defined, we can use the following information:
- Let \( x \) be the number of hot chocolates sold, priced at $1 each.
- Let \( y \) be the number of apple ciders sold, priced at $2 each.
The total revenue generated from selling hot chocolate and apple cider can be represented with the equation:
\[ 1 \cdot x + 2 \cdot y \]
To ensure that the revenue is at least $250, we can create the following inequality:
\[ x + 2y \geq 250 \]
To write this inequality in standard form \( Ax + By \geq C \), we can rearrange it:
\[ -x - 2y \leq -250 \]
Thus, the standard form of the inequality representing the revenue generated by selling hot chocolate and apple cider is:
\[ x + 2y \geq 250 \]
