Toby buys a new MP3 player for a price of 45.50. What is the total amount hoa credit card is charged if th salea tax is 7%?

GarryVolchara [31]

For sales tax, you just have to multiply the percentage by the number. So you can only have one step, add 1 after you divide the percentage by 100.
45.5•1.07=48.685
The cent only goes to the hundredths, so we have to round.
The total amount is $48.69.
