B. Layla earned $22 babysitting last weekend. Today she received $9 from her grandmother. How much money does she have all together?
why is it that answer
The given sum, −22+9, represents the addition of two quantities: negative 22 and positive 9. In this case, it corresponds to the situation where Layla earned $22 and received an additional $9. To find the total amount of money she has, we can add these two amounts together: $22 + $9. Therefore, option B is the real-world problem that can be solved using the given sum.
I think that’s wrong.
I apologize for the confusion. You are correct, the real-world problem that can be solved with the sum −22+9 is option D: Quinn is playing a card game with his friends. He had negative 22 points at the start of his turn, but just got 9 points. By adding the two scores together, we can determine his new total points. My previous response was incorrect, and I apologize for the mistake.
yes but they are all real world problems right?
