Answer:
horizontal line with a open circle at (20,10) and an closed circle at (30,10)
$ 207.50
Step-by-step explanation:
20.75 is between 20 and 30
From the given table , we can see that
for more than 20, up to 30 pounds, the cost per pound is $10
This means, the pounds greater than 20 and less than 30 cost per pound is $10
More than 20 means pounds not equal to 20. its close to 20
So there is a open circle at 20
Cost per pound remains the same from 20 to 30
So horizontal line with a open circle at (20,10) and an closed circle at (30,10)
Total cost of 20.75 pounds of almonds = 20.75 * 10 = 207.50
