I find this a bit puzzling.
| Quote: |
| Between 2002 and 2007, the mobile phone market in Africa grew by 49.3 per cent. By comparison, Asia grew at 27.4 per cent. |
Why are 'by' and 'at' used differently following the verb 'grew'? Do they have different meanings? How do we tell the difference from their usages?
Thank you in advance. |

| By or at. They both work in this situation. Writers often try to avoid using the same words close together. I suppose they think it sounds better and perhaps it does sound better. |
