To formulate the inequality that describes Sophie's spending on packages of hot dogs and buffalo wings, we can use the following variables:
- Let \( x \) represent the number of packages of hot dogs.
- Let \( y \) represent the number of packages of buffalo wings.
Given the costs:
- Each package of hot dogs costs $2, which contributes \( 2x \) to the total cost.
- Each package of buffalo wings costs $5, which contributes \( 5y \) to the total cost.
Sophie wants to spend under $66. This leads us to the inequality that represents her budget:
\[ 2x + 5y < 66 \]
This is the inequality in standard form representing Sophie's situation regarding the purchase of hot dogs and buffalo wings.
