Your parents gave you $225 to spend on a weeklong school trip. You have budgeted $23 per day for snacks and souvenirs.

Complete the equation to represent this situation, where y is the amount of spending money you have left in your budget and x is the number of days you have been on the trip.
y = _ x + _

1 answer

To represent the situation, we need to express how much money you have left after spending on snacks and souvenirs over a certain number of days.

You start with $225, and you spend $23 each day.

  1. Your total spending over \( x \) days is \( 23x \).
  2. The amount of spending money you have left after \( x \) days is the initial amount minus the total spending.

Putting this together, we can form the equation:

\[ y = -23x + 225 \]

So, in the equation format you've provided, it would be:

y = -23x + 225
