I need help!! Here are the prices for cans of juice that are the same brand and the same size at different stores.

1. Which store offers the best deal?
Store X: 4 cans for $2.48 Store Y: 5 cans for $3.00 Store Z: 59 cents per can

2. Explain your reasoning.

Answers:

To find the best deal, we'll need to find the unit price. This is the price for one can, or the price per can.

To find the price per can, we divide the total cost over the number of cans.

We see that Store Z offers the best deal since the unit price (59 cents per can) is the cheapest of the three stores.

Extra info (optional section)

If you're curious why we divide in the order we did, you can think of it like this:

Store X charges $2.48 for 4 cans. That means we can set up the ratio shown below

4 cans : 2.48 dollars

The unit price applies to 1 can. To turn that "4 cans" into "1 can", we divide both sides by 4

4 cans : 2.48 dollars

4/4 cans : 2.48/4 dollars divide both sides by 4

1 can : 0.62 dollars

1 can : 62 cents

The same sort of steps will be done for Store Y as well. So that is why we divide the total cost over the number of cans to get the unit price.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
