Step-by-step explanation:

I would guess that they added 42 and 45 and then added 1 for their mistake. That might be a bit of stretch, but that is what I think

Yes she made an error.

Step-by-step explanation:

42/45 = 0.93333

0.93333 * 100 = 93.3333

I'm not sure what she did wrong but maybe she added 3 to the 45 total to get 42/48 = 87.5 which rounds to 88.
