Question

based on the graph, what is the unit rate?

a. 5 oz of water per 1 scoop mix
b. 10 oz of water per 1 scoop mix
c. 1 oz of water per 1 scoop mix
d. 2 oz of water per 1 scoop mix

Explanation:

Identify a clear point on the graph

The horizontal axis represents the "Amount of Mix (scoops)" and the vertical axis represents the "Amount of Water (oz)". Looking at the line, it passes through several grid intersections:

• \((2, 10)\)
• \((4, 20)\)
• \((6, 30)\)
• \((8, 40)\)

Calculate the unit rate

The unit rate is the ratio of the vertical value (Amount of Water) to the horizontal value (Amount of Mix):

$$ \text{Unit Rate} = \frac{10\text{ oz}}{2\text{ scoops}} = 5\text{ oz per scoop} $$

Match with the given options

The calculated unit rate of \(5\text{ oz of water per 1 scoop mix}\) corresponds to option A.

Answer:

• (A) 5 oz of water per 1 scoop mix (Correct answer)
• (B) 10 oz of water per 1 scoop mix
• (C) 1 oz of water per 1 scoop mix
• (D) 2 oz of water per 1 scoop mix
