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

Sagot :

No, she is incorrect, to find the unit price you would divide the total price by the number of items. In this case 2.99/6 and that would be your unit price, in this case about ¢50.

For this case, the unit cost can be found through the following relationship:

[tex]Unit cost = \frac{total Cost}{Number Of Items}[/tex]

Substituting values in the given equation we have:

[tex] Unit cost = \frac{2.99}{6} [/tex]

[tex] Unit cost = 0.50 [/tex]

We note then that Devon's sister is wrong :

Answer:
