Given the statement:
You earn a score of 86.8 on a standardized exam. Your score is 140% higher than your friend's score on the standardized exam.
Determine your friend's score.
Solution:
The friend's score can be solved by the equation,
1.4x = 86.8
Solve for x.
To do so,we simply needed to divide both sides of the equation by 1.4.
1.4x/1.4 =86.8/1.4
x = 62
Final answer:
Your friend's score is 62.
