For every order, show how it compares with the customer's first order. Return id, name, total, first_total (the total of that customer's first order) and pct_vs_first (the percentage change from the first order, rounded to 1 decimal place). A customer's orders are ordered by order_date, then id. Sort the output by name, then order_date, then id.
