Last month, his total sales were $23600. He allocated 20% of his total earnings to savings and the rest of the money to his monthly expenses. How much were his monthly expenses last month?

conversations.value: Robert earned a commission of $23600 x 10/100 = $2360.
  So, he earned a total of $1250 + $2360 = $3610.
  And, he saved $3610 x 20/100 = $722.
  Therefore, his total expenses last month was $3610 - $722= $2888
