Question

A fireworks store is offering 15% off all fireworks. If you come to the store on the fourth of July, you get an extra 15% off the already discounted prices. What will you pay for a firework pack that originally costs $112.25?

Answer 1

You know that the store is offering 15% off all fireworks. You can write it as a decimal number by dividing it by 100:

`(15)/(100)=0.15`

According to the information given in the exercise the firework pack originally costs $112.25. So, applying the first discount of 15%, the cost would be:

`112.25dollars-(0.15)(112.25dollars)=95.4125dollars`

If you get an extra discount of 15% off the already discounted prices, you will pay the following amount of money in dollars:

`95.4125dollars-(95.4125dollars)(0.15)=81.10dollars`

Therefore, the answer is: $81.10
