Respuesta :

Answer:

819.2

Step-by-step explanation:

you find 20% of 1,600 which is 320 and subtract from the total 1,600-320=1,280 and subtract another 20% the same way since it is 20% annually which is 1,280-256=1,024 and subtract one more 20% which would be 1,024-204.8=819.2 which is your answer

Hope this helps!
