Answer:
The drink cost $2
Step-by-step explanation:
The answer can be seen logically.
If a liter of the drink equals 10 deciliters, then:
2 L = 20 dL
And if a deciliter of the drink equals $ 0.10 then:
20dL * $ 0.10 = $ 2
It could be concluded that a drink containing 2L has a value of $ 2
Answer can also be found by rule of three:
1dL = 0.10
20dL = X
Clearing the X equals:
X = 20 $ dL ($ 0.10)
X = $ 2
