When a number is decreased by 6%, the result is 72. What is the original number to the nearest tenth?

Answer 1

9514 1404 393

Answer:

76.6

Explanation:

The number remaining (72) after the 6% decrease is 94% of the original value (x). Then ...

72 = 0.94x

72/0.94 = x ≈ 76.6

The original number is about 76.6.
