Question

Which unit rate is the lowest price per ounce?

Choice A: 6 ounces of raisins for $1.49
Choice B: 13 ounces of raisins for $3.59
•Choice A
•Choice B
•The Unit rates are equal
• The unit rates cannot be determined

Answer 1

The first thing to do is find the unit rate for both

Choice A: 6 oz for 1.49
To get 6 to 1 you have to divide by 6. What you do to one side you must do to the other... So:
1.49/6=0.2483333
Round to the nearest tenth. 0.25
Choice A unit price is 0.25

Choice B: 13 oz for 3.59
To get 13 to 1 you need to divide by 13. What you do to one side you must do to the other... So:
3.59/13=0.2761
Round to the nearest tenth. 0.28

Then compare the two.
Answer: Choice B is a higher unit price.

Hope this helps!
