Answer:
20 blocks per pound.
Explanation:
In this question we have to determine the approximate number of blocks per pound, means we have to determine the slope of the given line in the graph.
Here end points of the line are origin (0,0) and (5,100).
Now the slope will be m = (y - y')/(x - x') = (100-0)/(5-0) = 100/5 = 20
Therefore the answer will be 20 blocks per pound.
