When a number is increased by 8.7%, the result is 39. What is the original number to the nearest tenth?

35.88

Step-by-step explanation: So if something is marked up by 8.7% it means, it is 108.7% of the original number.

So we can convert 108.7% to a decimal by dividing 108.7 by 100, which equals 1.087.

So if we want to find the original number, all we have to do is divide 39 by 1.087.

This will give us 35.88 as the original number rounded to the nearest tenth.
