To calculate the total cost of the board game including sales tax, follow these steps:
-
Determine the sales tax in decimal form:
Since the sales tax is given as 5%, we convert this to a decimal by dividing by 100:
\[ 5% = \frac{5}{100} = 0.05 \] -
Calculate the sales tax amount:
Multiply the cost of the board game by the sales tax rate:
\[ \text{Sales tax} = \text{Cost of board game} \times \text{Sales tax rate} = 10.25 \times 0.05 \]
\[ \text{Sales tax} = 0.5125 \] -
Calculate the total cost:
Add the sales tax to the original cost of the board game:
\[ \text{Total cost} = \text{Cost of board game} + \text{Sales tax} \]
\[ \text{Total cost} = 10.25 + 0.5125 = 10.7625 \] -
Round to two decimal places:
Typically, monetary values are rounded to two decimal places:
\[ \text{Total cost} \approx 10.76 \]
So, the total cost of the board game, including sales tax, is $10.76.
