Answer:
No, incorrect. It should be -13. 56 unit
Step-by-step explanation:.
I am overcharged 4.52 unit on my cell phone 3 months in a row.
So, net amount I am overcharged = [tex]4.52 \times 3 [/tex] unit
= 13.56 unit
So, in the next bill there should be an adjustment of - 13.56 unit. But, here it is given - 13.28 unit only. So, this is incorrect.
