Let 'x' represent the amount of 50% mixture used, then '20-x' represents the amount of 10% mixture used
0.25(20) = 0.50x + 0.10(20-x)
solving for 'x' we have x=7.5
20-7.5 = 12.5
7.5 pounds of 50% mixture should be combined with 12.5 pounds of 10% mixture
Step-by-step explanation:
The total income would be $650 million.
Isolate the B. Note the equal sign. What you do to one side, you do to the other. Subtract C and A from both sides
B + A (-A) + C (-C) = D (-A) (-C)
B = D - A - C
B = D - A - C is your answer
hope this helps
