Answer:
When 4864 books are sold
Step-by-step explanation:
Create an equation where x is the number of books produced:
The first method will be represented by 10.75x + 82,910
The second method will be represented by 23.25x + 22,110
Set these equal to each other and solve for x:
10.75x + 82,910 = 23.25x + 22,110
82,910 = 12.5x + 22,110
60,800 = 12.5x
4864 = x
So, the costs will be the same for both methods when 4864 books are sold
Answer:

Step-by-step explanation:
percentage = (discount/total amount)*100
= (8.40/28)*100=30%
Answer:
Step-by-step explanation:
2 1/2 + x = 5 1/3 Change the mixed numbers to improper fractions
5/2 + x = 16/3 The lowest common multiple is 6. Multiply by 6
5*3 + 6x = 16*2
15 + 6x = 32 Subtract 15 from both sides.
6x = 32 - 15
6x = 17 Divide by 6
6x/6 = 17/6
x = 2 5/6
Check
5/2 + 17/6 = 16/3
15/6 + 17/6 = 32/6
32/6 = 32/6 The question checks.
