.) Which pair of numbers has an LCM of 16?
2 and 12
5 and 12
6 and 12
3 and 12

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

step-by-step explanation:

left be aligning the decimal points is required to not required see the number of digits to the right

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
