Choose

1

answer:

\newline

(A)

51

euros

\newline

(B)

-51

euros

Money Decrease Explanation: Kai and their friends are paying for their meal, which means they are spending money. When you spend money, the amount of money you have decreases. This decrease is represented by a negative number because you have less money than you started with.
Bill Amount: The bill is for $51$ euros. Since this is the amount they are spending, the change in the amount of money they have is $-51$ euros. This is because they are giving away $51$ euros to pay for the meal.
