a bus ticket is $40 plus 5% tax.

40 * 1.05 =

how did you get 1.05

Ok, 5% = 5/100.

Thus, 5% tax is equal to 0.05.
The tax is equal to 0.05 * (the before tax cost = 40). Then, you add the price of the ticket back.

You can take a shortcut by doing 100% + 5% = 105% * 40 = 1.05 * 40 = ?

100 = 100%

0.05 = 5%

You could do the same problem by first taking 5% of 40, and then adding the product to 40.

To find the total cost of the bus ticket including the 5% tax, you can follow these steps:

1. Calculate the tax amount: Multiply the ticket price by the tax rate of 5%.
Tax Amount = Ticket Price * (Tax Rate/100)
Tax Amount = $40 * (5/100)
Tax Amount = $2

2. Add the tax amount to the ticket price to get the total cost:
Total Cost = Ticket Price + Tax Amount
Total Cost = $40 + $2
Total Cost = $42

Therefore, the total cost of the bus ticket including the 5% tax is $42.
