Answer:

The original number was 18.1.

Step-by-step explanation:

This question can be solved using a simple rule of three.

When a number is decreased by 17% the result is 15.

So 15 is 100-17 = 83%. The original number is 100%. Then

15 - 0.83

x - 1

[tex]0.83x = 15[/tex]

[tex]x = \frac{15}{0.83}[/tex]

[tex]x = 18.1[/tex]

The original number was 18.1.
