Answer :
Answer:
Bottles (b) = 5
Step-by-step explanation:
1. 1 1/8B + 15/16 = 6 9/16
2. 1 1/8B = 105/16 - 15/16
3. 1 1/8B = 90/16
4. (9/8) (8/9B) = 90/16 (9/8)
5. B = 10/2 = 5
The number of bottles b should be 5.
Given that,
- Mora preparing her pack for a hike.
- Her empty pack weighs 15 by 16 pound.
- She adds some water bottle that each weigh 1 1 by 8 pound.
- Now Mora's pack weighs 6 9by 16 pounds.
Based on the above information, the calculation is as follows:
[tex]1 \frac{1}{8}B + 15\div 16 = 6 \frac{9}{16}\\\\ 1 \frac{1}{8}B = \frac{105}{16} - \frac{15}{16}\\\\1 \frac{1}{8}B = 90\div 16\\\\(9\div 8) (8\div 9B) \\\\= 90\div 16 (9\div 8)\\\\B = 10\div 2[/tex]
= 5
