The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $7500 to rent
Oduvanchick [21]
This seems to be an incomplete question. I think you want to know the amount of sugar at which both company will charge the same. Based on this idea, i am answering the question. 
Let us assume the quantity of sugar = x
Then
For company A, charge = 7500 + 125.25x
For company B, charge = 5995 + 200.50x
Now
7500 + 125.25x = 5995 + 200.50x
7500 - 5995 = 200.50x - 125.25x
1505 = 75.25x
x = 20
From the above deduction it can be concluded that the quantity of sugar at which the prices of both the companies will be the same is 20 ton.

5b -7 + 7 = 58 + 7

5b = 65
