Victoria was attempting to read a book within a week. On Monday, she had read

2x12 = 24 u |
5x12 = 60 u |
7x12 = 84 u |

+ 371 |
- 371 |

Friday |
11x7 = 77 u |
1x7 = 7 u |
12x7 = 84 u |
Number of pages that Victoria read
= 77 u - 24 u
= 53 u
53 u = 371
1 u = 371 ÷ 53 = 7
Total number of pages
= 84 u
= 84 x 7
= 588
Average number of pages to read per day
= 588 ÷ 7
= 84
Answer(s): 84
