Final answer:
By adding the amount raised by King's class ($233) and Mr. Jones's class ($243), the total money raised for the library books is $476.
Step-by-step explanation:
The two classes raised a total sum of money by adding the amounts each class collected individually. King's class raised $233 and Mr. Jones's class raised $243. To find the total money raised, we simply add these two amounts together.
Calculating the total money raised:
- King's class: $233
- Mr. Jones's class: $243
- Total money raised: $233 + $243 = $476
Therefore, the total amount of money raised by both classes for the library books is $476.
