Answer 1

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.

Answer 2

Answer:

x/5

X-(x/5)= 380

X-380

Step-by-step explanation:

Let the previous amount of the desk be X

The desk had a 20% off of the previous fee

New/recent amount of the desk is $380

We are going to get the previous price of the desk before the discount

20/100×(X) (amount of money deducted from the original price)

= x/5

Now we solve for the original price of the desk prior to the deduction

X-(x/5)= 380

(5x-x)/5= 380

X= 380×5÷4

X= $475
