Answer: This is a guess I am not that smart
c. Both have been impacted by overgrazing and radioactive pollution.
Let C = the Chinese books.
Let E = the English language books.
C = 4/5 E
E - 300 = C - 180 Notice how you get this equation. You take 300 away from the English books and 180 from the Chinese and according to the question, you get an equal number of both. Put c = 4/5E into the second equation.
E - 300 = 4/5 E - 180 Add 300 to both sides.
E = 4/5 E - 180 + 300
E = 4/5 E + 120 Now subtract 4/5 E from both sidies.
E - 4/5 E = 120
1/5 E = 120 Now multiply by 5
E = 120 * 5
E = 600
So the number of books are
600 written in English
4/5 of 600 = 2400 /5 = 480 Chinese books.
English 600
Chinese 480
Given:
The total cost of the order is

where, T is the total cost, b is the number of bath towels, and w is the number of wash cloths.
Her budget is $85.
To find:
The constraints, so that she can order a maximum of washcloths or bath towels.
Solution:
We have,

Her budget is $85. So, total cost is less than or equal to 85.
...(i)
For maximum number of bath towels, the number of wash cloths is 0.

Divide both sides by 6.
For maximum number of wash cloths, the number of bath towels is 0.


Divide both sides by 2.


Therefore, the required constraints for maximum of washcloths or bath towels are
and
respectively.
