Answer
73
Step-by-step explanation:
you need to subtract the 26 from 120 to get 94 divide that by 2 to get 47 so thats haw many calls they each made then add on the 26 to find her amount to get 73
I would pick the “D” the same line
Plot the point 123 on the line and go to the right 235 units.
because there is the big number, just draw the line begin with 123 to 400.
each unit might increase by 10.
123, 133, 143, etc
you can increase bigger if you want
