Answer:
D, 64%
Step-by-step explanation:
To solve algebraic equations, you have to do the inverse or opposite, so because you are multiplying x by 50 on one side and x wants to be alone, you have to do the opposite which is divide by 50 to get x*1 or just x (because 50/50 equals 1) and what you do on one side of the = sign you do on the other, so 32/50 = 0.64. Then to make a percent you move the decimal to the right by 2 places and you get 64%
