Answer:
S = 380 - 380*80%
Step-by-step explanation:
Given:
- The original price of the desk: $380
- Discount: 20%
So, the new price of the desk after discounting is:
380(100% - 20%)
= 380*80%
= 304$
The amount of money saved: 380 - 304 = 76$
Hence, the equation can be used to determine the amount of money saved is:
Saving = 380 - 380*80%
Hope it will find you well.
