Jojo runs a luxury cab service in the city. There are 600 vehicles in Jojo's fleet, out of which 50% are sedans and 50% are SUVs. Each vehicle is routinely taken out of service and sent to Dino's auto-shop for maintenance and repair. On average, a sedan is sent to the auto-shop shop 3 times every month, and an SUV is sent to the auto-shop 3 times every month (Assume 30 days in a month). When sent for maintenance and repair, each vehicle spends an average of 1.3 days in the auto-shop before it is back in service. What is the average number of Jojo's vehicle out of service in Dino's auto-shop?
