1. Relate the amount spent to the amount left

Since Alice receives the same amount of pocket money every day, the amount she spends is inversely related to the amount she has left. Therefore, the day she spent the most money is the day she had the least amount of money left.

2. Identify the day with the least amount of money left from the graph

Looking at the line graph, the lowest point corresponds to Tuesday. Thus, she had the least money left on Tuesday, meaning she spent the most on that day.

Answer

Tuesday
