Antonio is buying a stereo, speakers, and amplifiers for his car audio system. he is choosing among 4 models of stereos and 3 styles of speakers. if he has 36 different choices, how many kinds of amplifiers must there be?

The answer is 3. I just did this.

Step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
