only b
both a and b
neither a nor b

pls respond soon

It's Neither A or B

Step-by-step explanation:

It is neither of them because A and B are both having two x values that are equal to different y values.

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
