Explain why 6*5*4*3*2*1*+4*3*2*1-3*2*1 is composite

6*5*4*3*2*1+4*3*2*1-3*2*1 =

6*5*4*3*2*1+(4-1)*3*2*1=

6*5*4*3*2*1+3*3*2*1=

3*2*1*(6*5*4+3)

this number has more than 2 factors, therefore is composite

i pretty sure it is

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
