A bottle

A bottle full of cola weighs 1,320 g. If we drink three-tenths of it, it will weigh 1,008 g. How much does an empty bottle weigh?

Final Answer:

f =  280 g

Step-by-step explanation:

f + v = 1320 f + v  3/10 v = 1008  f + 7/10v = 1008  (1320v)+7/10v=1008  (1320v)+7/10 v=1008  3v=3120  v=33120=1040  v=1040  f=1320v=13201040=280 g
