39. Which set of ordered pairs represents y as a function of X?
A {0.0) (-1,2).(-1, -2), (-2, 4), (-2,-4)}
B.
{(0.0), (1, 1), (2.4), (3,9). (3.16)}
C. {0.0), (0.1),(0,2), (0.-1), (0-2)
D
{(0, 0).(-1,-0.5), 6-2 -1).(-3 -1.5), (-4.-2)}

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
