I believe the agent has $1,290.63 left.
Because... 30% of 10,631.25 is $3,189.38( the exact was 3,189.375 but I rounded up). That's how much the agent has. Since it is $350 a night, 350 x 5= $1,750.00. Then you add the 8.5% to the $1,750 and you get $1,898.75. That will be the total amount of money he will spend. So you will have to subtract $1,898.75 from $3,189.38 and the amount is $1,290.63. The remaining amount is $ 1,290.63. I hope this helps :)
