Answer: -7.408%
Explanation: The formula for percent error is:
(experimental - theoretical) / theoretical * 100. The experimental value is 50, or your guess. The theoretical value is 54, or the actual value. The theoretical value is the value it should be.
(50-54)/54 = -.074 * 100 = -7.408%
Since there is a 5 to the right of the decimal, you will round the number immediately to the left of the decimal up. So the nearest whole number would be 71.
C-d=b add to both sides d and will get
c-d+d=b+d
c=b+d
