Answer:
- Pet store 2 is offering the better price.
- The price by which it is cheap is: $ 0.315
Step-by-step explanation:
Pet Store--1
They are offering the flea treatment for 40 percent off plus an additional 25 percent off their regular price of $33.
This means that the cost of treatment after a off of 40% is:
33-0.40×33=$ 19.8
Now after a additional discount of 25% , a person has to pay (100-25)%=75% of the above discounted price.
i.e. 0.75 of 19.8
= 0.75×19.8
= $ 14.85
Hence, the total cost of treatment in store -1 is: $ 14.85
Pet Store--2
They are offering the same flea treatment for 55 percent off plus an additional 5 percent off their regular price of $34.
This means that the cost of treatment after a off of 55% is:
34-0.55×34=$ 15.3
Now after a additional discount of 5% , a person has to pay (100-5)%=95% of the above discounted price.
i.e. 0.95 of 15.3
= 0.95×15.3
= $ 14.535
Hence, the total cost of treatment in store -1 is: $ 14.535
Hence, the location which is offering the better price is: Pet Store-2
The amount by which it is cheaper than store 1 is:
= 14.85-14.535
= $ 0.315
