To represent the situation where \( y \) is the amount of spending money left in your budget and \( x \) is the number of days you have been on the trip, you can use the following equation:
- Starting Amount: You start with \( $314 \).
- Daily Spending: You spend \( $25 \) per day.
The equation representing the situation can be formulated as follows:
\[ y = 314 - 25x \]
In this equation:
- \( y \) is the amount of spending money you have left.
- \( 314 \) is the initial amount of money given to you.
- \( 25x \) represents the total amount spent after \( x \) days of spending \( $25 \) each day.
This equation will help you determine how much money you have left as the number of days \( x \) increases.
