Final answer:
Josiah could have planted a total of 49 seeds, as this is the only number that allows for equal groups (7 rows of 7 seeds each) when planting more than one row.
Step-by-step explanation:
The question asks to determine what could be the total number of seeds Josiah plants, given that he plants them in rows with the same number of seeds in each and considering he plants more than one row. When you have equal groups of items (in this case seeds), the total number must be a multiple of the number of items in each group (the number of seeds per row). Looking at the options given, the only number that is not a prime number and can represent multiple equal groups is 49. Since 49 is 7 times 7, it implies that Josiah could have 7 rows with 7 seeds in each row.
