Statement 1
The average arithemetic mean number of customers per car leading to the outdoor movie last right was 2
From the arithemetic mean of $$\frac{EFX}{EF}$$
$$Average\ customer\ per\ car\ =\frac{Total\ Customer}{No\ of\ cars}$$
Average customer per car= 2 but we were not given any information on Total customers so we cant find total number of cars.
Hence statement 1 is INSUFFICIENT.

Statement 2
Total receipts at the outdoor movie last night were 4500 dollars at 5dollar per customer.

$$So\ Total\ customer\ =\frac{Total\ receipts}{receipts\ per\ customer}=\frac{4500}{5}=900customers$$
But we cannot find the total number of cars from this piece of information
Hence statement 2 is INSUFFICIENT.

combining statement 1 and 2 together
Total customers = 900
Average customer per car = 2
$$Average\ customer\ per\ car=\frac{Total\ Customers}{Total\ number\ of\ Cars}$$
Make Total number of Cars the subject formular.
$$Total\ numbers\ of\ Cars=\frac{Total\ Customers}{Average\ Customer\ per\ car}$$
$$Total\ numbers\ of\ Cars=\frac{Total\ Customers}{Average\ Customer\ per\ car}=\frac{900}{2}=450cars$$
$$Both\ statement\ combined\ together\ are\ SUFFICIENT.$$
$$answer\ is\ Option\ C$$
