To calculate the total cost of the video game including sales tax, we first need to calculate the sales tax amount.
-
Calculate the sales tax:
- Game price: $30
- Sales tax rate: 7%
Sales tax = Game price × Sales tax rate
Sales tax = $30 × 0.07 = $2.10 -
Calculate the total cost: Total cost = Game price + Sales tax
Total cost = $30 + $2.10 = $32.10
So, Rebecca paid $32.10 for the video game including sales tax.
