The answer is: 180 . ______________________ Explanation: _______________ 30 % = 30/100 = 0.30 ; ____________________________ 54 = 0.30 * x ; ↔ 54 = 0.3 x; _____________________________ → Divide EACH side fo the equation by "0.3" ; to isolate "x" on one side of the equation; and to solve for "x" ______________________________ → 54/0.3 = 0.3x/0.3 ; ___________________ → 180 = x; ↔ x = 180 ; which is our answer. ___________________________________________
