###Human: Ed booked a hotel while he was on vacation. Staying at the hotel cost was $1.50 per hour every night and $2 per hour every morning. If Ed had $80 and he stayed in the hotel for 6 hours last night and 4 hours this morning, how much money was he left with after paying for his stay at the hotel?, ### Assistant: Ed spent $1.50 x 6 = $9 for staying in the hotel last night.
He spent $2 x 4 = $8 for staying in the hotel this morning
So, the total money he spent in the hotel is $9 + $8 = $17.
Therefore, he still has $80 - $17 = $63 left after staying in the hotel. 
 So the answer is :  63
