To solve the problems presented, let's go through each one step-by-step.
4a. Determine the Sales Tax
- Price of the board game: $17.99
- Sales tax rate: 7% or 0.07
To calculate the sales tax, use the formula: \[ \text{Sales Tax} = \text{Price} \times \text{Tax Rate} \]
Substituting the values: \[ \text{Sales Tax} = 17.99 \times 0.07 = 1.2593 \]
Now, we round this to the nearest hundredths place: \[ \text{Sales Tax} \approx 1.26 \]
So the answer for part 4a is $1.26.
4b. Calculate the Total Price
Now, to find the total price including sales tax: \[ \text{Total Price} = \text{Price} + \text{Sales Tax} \]
Using the previously calculated sales tax: \[ \text{Total Price} = 17.99 + 1.26 = 19.25 \]
Therefore, the total amount you will pay at the register for the board game, including sales tax, is $19.25.
