With tax, instead of paying 100% of the price, you will pay 100% + 4.5%, or 104.5% of the price.
Therefore, you should multiply the price by 1.045, choice C.

4 1/2% = 4.5% = 0.045
Since this is Tax, and you add tax on to the total, you want the total + the amount of tax: 1 (representing the 100% of the original cost) + 0.045 = 1.045....
Multiply this number by the original cost. Therefore, c is the correct answer.

C.
Multiply the amount by the total including tax.
So 4.5% on $15 would be a total amount of 1.045 X 15, or15.675 (round to $15.68).

Yeah, it's C, but it's not a shortcut; it's the normal way you would do it.

It is "c". Pay more attention when you shop and you'd not ask such questions.
