In a library open from Tuesday to Saturday inclusive, we counted, day by day, the number of books lent during a week and we obtained the results in the following table:
| Tuesday | 117 |
| Wednesday | 147 |
| Thursday | 42 |
| Friday | 90 |
| Saturday | 124 |
1. Calculate the total number of books loaned during the entire week.
2. Calculate the average number of books loaned, per day, during this five-day week.
