The question in English

1.5 hours for tuning; 0.2 hours for cleaning the battery; 0.75 hours for changing the oil and engine filter; 1.45 hours for changing and aligning lights; and 1.3 hours for repairing the air conditioning system. The hourly rate is 32.8 soles; how much does it cost to repair the car?

(1.5+0.2+0.75+1.45+1.3)=5.2\ hours
