It is not safe to walk on ice if it is less than 4 inches thick. define a variable and write an inequality for thickness of ice on which it is soft to walk. graph the solution

the first one, all those points on the line just make a strait line.

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
