Final answer:
Both Zach and David have arranged their quarters in such a way that each has a total of 30 quarters. by multiplying the rows by the columns for each arrangement, it is clear that neither has more quarters than the other.
Step-by-step explanation:
The question is asking us to compare the total amount of quarters between two arrangements: one with 6 rows and 5 columns and another with 5 rows and 6 columns. To find out who has more quarters, we can simply calculate the product of rows and columns for each arrangement.
In Zach's arrangement of 6 rows and 5 columns, the total number of quarters is:
- 6 rows × 5 columns = 30 quarters
In David's arrangement of 5 rows and 6 columns, the total number of quarters is:
- 5 rows × 6 columns = 30 quarters
Comparing the two products, we can see that both Zach and David have the same number of quarters, which is 30 in each case. Therefore, neither Zach nor David has more quarters than the other.
