Answer:
Devon's sister is not correct.
Cost of each drink: $0.50.
Step-by-step explanation:
We have been that Devon is trying to find the unit price on a 6-pack of drinks on sale for $2.99.
His sister says that at that price, each drink would cost just over $2.00.
Since each pack consists 6 drinks, so cost of each drink would be $2.99 divided by 6, therefore, Devon's sister is not correct.
[tex]\text{Unit price}=\frac{\$2.99}{6\text{ drinks}}[/tex]
[tex]\text{Unit price}=\frac{\$0.4983}{\text{ drink}}[/tex]
[tex]\text{Unit price}\approx \frac{\$0.50}{\text{ drink}}[/tex]
Therefore, the cost of each drink would be $0.50.
