Answer:

E

Step-by-step explanation:

.03(50) + 0x = (50-x).05  How much 3% salt much be added to zero percent salt to create a mixture that is 5 percent salt.

3(50) = (50 - x)5  I multiplied through by 100 to clear the decimals

150 = 250 - 5x  Distribute the 5

-100 = -5x  Subtract 100 from both sides of the equation

20 = x divide both sides by -5
