If you horizontally stretch the linear parent function, f(x) = x, by a factor of 3, what is the equation of the new function?

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

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

what level of math? also i don't need to be paid if i can you.
