<human>:  A dance studio offers lessons to students. It costs $25 per session to rent the studio plus $1.50 per student per session. At present, the dance studio has 10 students and is rented 3 days a week. How much are the expected earnings of the dance studio in a month?
<bot>: How much do the students pay? ** The total earnings from 10 students is $1.50 x 10 = $<<1.50*10=15>>15 per session.
How much does the studio earn? ** So the total earnings per session is $15 + $25 = $<<15+25=40>>40.
How much does the studio earn in a week? ** Thus, every week the dance studio earns $40 x 3 = $<<40*3=120>>120.
How much does the studio earn in a month? ** Therefore, it will earn $120 x 4 = $<<120*4=480>>480 in a month.
