Answer: Each bottle contains 360 milliliters.
Explanation:
Let's call the amount of milliliters in each bottle "x".
Fubara has 3 full bottles, so the total amount of milliliters she has is 3x. She also has 20 milliliters more, bringing her total to 3x + 20.
Dayo has 2 full bottles, so the total amount of milliliters he has is 2x. He also has 140 milliliters more, bringing his total to 2x + 140.
Since they have the same amount of orange drink, we can set the two expressions equal to each other:
3x + 20 = 2x + 140
Subtracting 2x from both sides:
x + 20 = 140
Subtracting 20 from both sides:
x = 120
So each bottle contains 360 milliliters.
