Question

Devon is trying to find the unit price on a 6-pack of drinks on sale for 2.99$. His sister says that at that price, each drink would cost just over 2.00$. Is she correct? and how do you know? If she is not, how would Devon's sister find the correct price?

Answer 1

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.

$\text{Unit price}=\frac{\ 2.99}{6\text{ drinks}}$

$\text{Unit price}=\frac{\ 0.4983}{\text{ drink}}$

$\text{Unit price}\approx \frac{\ 0.50}{\text{ drink}}$

Therefore, the cost of each drink would be $0.50.

Answer 2

She is not correct, because $3.00 divided by 6 is 50 cents, so by using that equation she could evaluate that she is wrong and find the correct answer.
