Your parents gave you $300 to spend on a weeklong school trip. You have budgeted $27 per day for snacks and souvenirs.

Question

Write 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.

Answer 1

To represent the situation mathematically, we need to establish the total budget and the daily spending.

You start with a total budget of $300 and plan to spend $27 per day for snacks and souvenirs. Therefore, the amount spent after $x$ days can be expressed as $27x$.

The equation representing the amount of spending money you have left in your budget after $x$ days is given by:

$$y=300-27x$$

Here, $y$ is the amount of spending money left, $300$ is the initial budget, $27$ is the daily spending, and $x$ is the number of days you have been on the trip.
