answer:Apologies for the oversight. To handle cases like '6.60/month' along with '9.99/month' and '9.99 one time charge', we can use the SQL `IN` operator with a `VALUES` clause to specify the desired values. Here's the modified query: ```sql SELECT COUNT(*) as count, price, CAST(SUBSTR(price, 2) AS REAL) as casted_price FROM ( SELECT DISTINCT app_id, pricing_plan_id, price FROM apps_pricing_plans JOIN pricing_plans ON apps_pricing_plans.pricing_plan_id = pricing_plans.id ) AS distinct_pricing_plans WHERE price IN ('9.99/month', '9.99 one time charge', '6.60/month') AND casted_price >= 5 AND casted_price <= 10 GROUP BY price, casted_price ORDER BY count DESC, casted_price LIMIT 3; ``` In the modified query, I have replaced the `LIKE` operator with the `IN` operator to specify the desired values. The `VALUES` clause contains the three options: `'9.99/month'`, `'9.99 one time charge'`, and `'6.60/month'`. This will select rows where the price matches any of these three options.

answer:To select all values between prices 5.00 and 10.00, you can modify the `WHERE` clause to use a range comparison with the `casted_price` column. Here's the updated query: ```sql SELECT COUNT(*) as count, price, CAST(SUBSTR(price, 2) AS REAL) as casted_price FROM ( SELECT DISTINCT app_id, pricing_plan_id, price FROM apps_pricing_plans JOIN pricing_plans ON apps_pricing_plans.pricing_plan_id = pricing_plans.id ) AS distinct_pricing_plans WHERE casted_price >= 5.00 AND casted_price <= 10.00 GROUP BY price, casted_price ORDER BY count DESC, casted_price LIMIT 3; ``` In the modified query, the `WHERE` clause includes the condition `casted_price >= 5.00 AND casted_price <= 10.00`, which ensures that only values between 5.00 and 10.00 (inclusive) are selected.

answer:Apologies for the oversight. To handle cases with spaces in the price, you can use the SQL `LIKE` operator with wildcard characters (%) to match the desired range. Here's the modified query: ```sql SELECT COUNT(*) as count, price, CAST(SUBSTR(price, 2) AS REAL) as casted_price FROM ( SELECT DISTINCT app_id, pricing_plan_id, price FROM apps_pricing_plans JOIN pricing_plans ON apps_pricing_plans.pricing_plan_id = pricing_plans.id ) AS distinct_pricing_plans WHERE price LIKE '%%' AND casted_price >= 5.00 AND casted_price <= 10.00 GROUP BY price, casted_price ORDER BY count DESC, casted_price LIMIT 3; ``` In the modified query, I have replaced the `price IN` clause with `price LIKE '%%'`. The `%` wildcard characters match any sequence of characters, so this condition will match prices containing any characters between 5.00 and 10.00 (inclusive).
