Answer:
I'm pretty sure 381
Step-by-step explanation:
I added 80,60,30, and 40 then divided it by 1000 to get a standard.
then i multiplied eachone by the answer to 210/1000 (which is 38.1 rounded)
I made sure to add them togetger and make sure it equalled 1000 which it did.
therefore 80•38.1 ... = 381
