To calculate the total cost including tax at Starbucks, you'll need to know the tax rate applicable. However, I can help you understand how to calculate it if you have that information.
Assuming you're in a region with a sales tax rate of, for example, 7% (you'd need to adjust if your local tax rate is different), you can calculate the total cost as follows:
- Take the pre-tax price.
- Multiply the pre-tax price by the tax rate (convert the percentage to a decimal).
- Add the tax to the original price.
Here's the formula: \[ \text{Total Cost} = \text{Pre-Tax Price} + (\text{Pre-Tax Price} \times \text{Tax Rate}) \]
If we apply this to each option:
For A: $24.24
- Tax: $24.24 × 0.07 = $1.70 (approximately)
- Total: $24.24 + $1.70 = $25.94
For B: $23.16
- Tax: $23.16 × 0.07 = $1.62 (approximately)
- Total: $23.16 + $1.62 = $24.78
For C: $26.00
- Tax: $26.00 × 0.07 = $1.82 (approximately)
- Total: $26.00 + $1.82 = $27.82
For D: $22.25
- Tax: $22.25 × 0.07 = $1.56 (approximately)
- Total: $22.25 + $1.56 = $23.81
Based on a 7% tax rate, the options would yield the following total costs:
- A: $25.94
- B: $24.78
- C: $27.82
- D: $23.81
Please note that you will need the specific tax rate applicable in your region for an accurate calculation. Adjust the calculations accordingly based on the actual tax rate to find the total cost.
