Answer:

40

Step-by-step explanation:

(2/5)*n - 6 = 10                         Add 6 to both sides

(2/5)*n - 6 + 6 = 10 + 6             Combine

(2/5)*n = 16                               Multiply both sides by 5/2

(5/2)(2/5)n = 16*(5/2)

n = 80 / 2

n = 40

To know how many hits each day had, go to the end of the graph, and the closest number at the bottom is how many hits there were. This graph states that there were around 1900 hits on Tuesday, and 1300 on Monday. To get the answer we then take the difference, getting 600.
