You use a juice mix to make orange juice. You combine 12 ounces of the mix with 36 ounces of water. What is a unit rate that describes your juice?
12 ounces of water per ounce of juice mix
3 ounces of water per ounce of juice mix
1/3 ounce of water per ounce of juice mix
36 ounces of water per ounce of juice mix
To find the unit rate of water per ounce of juice mix, divide the amount of water (36 ounces) by the amount of juice mix (12 ounces):
[
text{Unit Rate} = frac{36 text{ ounces of water}}{12 text{ ounces of juice mix}} = 3 text{ ounces of water per ounce of juice mix}
]
So the correct answer is 3 ounces of water per ounce of juice mix. This means for every ounce of juice mix you use, you mix in 3 ounces of water.
