Calculate Current Drawing at 120V After 15.8% Voltage Reduction

[shimizua]

Homework Statement

If the resistance of the device were reduced by 15.8 percent, what current would be drawn at 120 V?

there was a first part of this question which i have already gotten. the question was
An electrical device draws 2.56 A at 120 V. If the voltage drops by 15.8 percent, what will be the current, assuming nothing else changes? so the resistance is 46.875

Homework Equations

ok so i believe that i would just do 120/(.158x46.875)

The Attempt at a Solution

when i did this i got like 16 A and it was said to be wrong. i am confused on what i did wrong.

Reducing by 15% means you keep 85% of the resistance. Multiply by .842, not .158.
