The tables in 3.3 will make $700 more than the other type of tables.
According to the code, the cost of the first type of table is $1000 and the revenue generated by it is $2000. The cost of the second type of table is $1500 and the revenue generated by it is $1800. So, the profit made by the first type of table is $2000 - $1000 = $1000 and the profit made by the second type of table is $1800 - $1500 = $300. Therefore, the first type of table makes $1000 - $300 = $700 more than the second type of table.
