Answer
Answer:
C. $0.15 per bag
Explanation:
Step1: Find price per bag for 50 bags
From the graph, for 50 bags, the cost is $20. So the price per bag is $\frac{20}{50}= 0.4$ dollars per bag.
Step2: Find price per bag for 150 bags
From the graph, for 150 bags, the cost is $45$. So the price per bag is $\frac{45}{150}=0.3$ dollars per bag.
Step3: Calculate the difference
The difference is $0.4 - 0.3=0.15$ dollars per bag.
