+# SQL Everyday \#133
+
+## Restaurant Growth
+
+Site: LeetCode\
+Difficulty per Site: Medium
+
+## Problem
+
+You are the restaurant owner and you want to analyze a possible expansion (there will be at least one customer every day).
+
+Compute the moving average of how much the customer paid in a seven days window (i.e., current day + 6 days before). `average_amount` should be *rounded to two decimal places*.
+
+Return the result table ordered by `visited_on` *in ascending order*. [[Full Description](https://leetcode.com/problems/restaurant-growth/description/)]
+
+## Submitted Solution
+
+```sql
+-- Submitted Solution
+WITH cte AS (
+    SELECT
+        visited_on
+        ,SUM(total_daily) OVER (ORDER BY visited_on ROWS BETWEEN 6 PRECEDING AND CURRENT ROW) AS amount
+        ,ROUND(AVG(total_daily) OVER (ORDER BY visited_on ROWS BETWEEN 6 PRECEDING AND CURRENT ROW), 2) AS average_amount
+    FROM 
+        (
+        SELECT
+            visited_on
+            ,SUM(amount) as total_daily
+        FROM Customer
+        GROUP BY visited_on
+        ORDER BY visited_on ASC
+        ) AS daily
+)
+SELECT
+    *
+FROM cte
+WHERE visited_on >= DATE((SELECT MIN(visited_on) FROM Customer) + INTERVAL 6 DAY)
