"lowest price per ounce" means what?

OpenStudy (schoolgeek15):

The cheapest?

OpenStudy (3mar):

Great! in other words: the smallest price per largest amount of chocolates!

OpenStudy (schoolgeek15):

Ok!

OpenStudy (3mar):

So What did you pick?

OpenStudy (schoolgeek15):

Umm, Choice B?

OpenStudy (3mar):

\[Rate_A=\frac{ 2.49 }{ 30 }=??\] \[Rate_B=\frac{ 3.32 }{ 40 }=??\]

This is a pretest that I am doing so I don't know how to do any of this. What do I do?

OpenStudy (3mar):

What I did is: I divided the price of chocolate by the amount of chocolate for cases A and B. no more! The smallest result/ratio is "the lowest price per ounce". Got it?

OpenStudy (schoolgeek15):

Ok

OpenStudy (3mar):

I am happy to hear that.

OpenStudy (schoolgeek15):

Wait, so is it they are equal?

OpenStudy (schoolgeek15):

What is the answer I am so confused :/

OpenStudy (3mar):

Right! They are equal..you got it!

OpenStudy (schoolgeek15):

Yay! Thank you!!!!

OpenStudy (3mar):

With my pleasure! Thank you for learning!

OpenStudy (3mar):

Thank you for the medal!
