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

1x11 = 11 u |
5x11 = 55 u |
6x11 = 66 u |

+ 301 |
- 301 |

Friday |
9x6 = 54 u |
2x6 = 12 u |
11x6 = 66 u |
Number of pages that Julie read
= 54 u - 11 u
= 43 u
43 u = 301
1 u = 301 ÷ 43 = 7
Total number of pages
= 66 u
= 66 x 7
= 462
Average number of pages to read per day
= 462 ÷ 7
= 66
Answer(s): 66
