20

Step-by-step explanation:

24.80-6.80=$18   that's what Britta spent on equal number of carrots and apples because $6.80 was spent on extra carrots only.

18/ .90=20 that means she got 20 apples and 20 carrots before she added $6.80 to buy some extra carrots

Thus, the number of apples Britta bought = 20
