To calculate the total amount Toby's credit card is charged, you need to find out the sales tax amount first. The sales tax is 7% of the price of the MP3 player.
Step 1: Convert the percentage to a decimal. Divide 7 by 100, which yields 0.07.
Step 2: Multiply the price of the MP3 player by the sales tax rate. So, 45.50 * 0.07 = 3.185.
Step 3: Add the sales tax amount to the price of the MP3 player to get the total amount charged on Toby's credit card. Therefore, 45.50 + 3.185 = 48.685.
Therefore, the total amount of Toby's credit card charged, including sales tax, is $48.685.
