There is a batch of coal at the port. First use 8 large trucks, each loaded with 5 tons; the rest will be transported by 5 small trucks, and the loading capacity of each small truck is (3/5) of the large truck, which happens to be transported at one time. How many tons of coal are there in total?
港口有一批煤．先用8辆大卡车运，每辆装5吨；剩下的改用5辆小卡车运，每辆小卡车的装载量是大卡车的(3/5)，恰好一次运完．这批煤共有多少吨？
