Answer 1

Situation 3 gives betters price.

Step-by-step explanation:

Given,

Situation 1: A discount of 15% and then 10% off that amount

Situation 2:  A discount of 10% and then 15% off that amount

Situation 3: A discount of 25%

To find the better situation.

Let us take the objects costs 100.

Formula

If the original price is a and there is b% discount or off the price will be a×$\frac{100-b}{100}$

Situation 1: A discount of 15% and then 10% off that amount

After 15 % discount the amount will be = 85

Then giving 10% off the amount will be = 85×$\frac{90}{100}$ = 76.5

Situation 2:  A discount of 10% and then 15% off that amount

After 10 % discount the amount will be = 90

Then giving 15% off the amount will be = 90×$\frac{85}{100}$ = 76.5

Situation 3: A discount of 25%

After 25% discount the price will = 75

Hence,

Situation 3 gives betters price.
