Look at the units. You need PRICE per OUNCE. So take the price and divide it by the number of ounces. Then compare the results.

OpenStudy (anonymous):

What do you think?

OpenStudy (anonymous):

B

OpenStudy (anonymous):

Nope. What do you get for the price per ounce for A?

OpenStudy (anonymous):

6.024...

OpenStudy (anonymous):

No. Divide price by ounces. Try again.

OpenStudy (anonymous):

Hello?

Choice A: What's the price?

OpenStudy (anonymous):

2.49

How many ounces?

OpenStudy (anonymous):

OK. To get price/ounce (price per ounce), divide the price by the number of ounces, i.e.\[\frac{ 2.49 }{ 15 } = ???\]

OpenStudy (anonymous):

0.16666

OpenStudy (anonymous):

Excellent. Now calculate the price per ounce for Choice B. What do you get?

OpenStudy (anonymous):

0.166 too

OpenStudy (anonymous):

Great. So every ounce of chocolate chips costs $0.1667. So what's your answer to the question?

OpenStudy (anonymous):
