569/ 9  x^2−153xy−12y

Step-by-step explanation:

S = 380 - 380*80%

Step-by-step explanation:

Given:

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%
