Question

Can you please help with 1 I did it but I don’t know if it is write

Answer 1

Given the table showing the Sale Amounts and the Sales Tax of 5%, you need to rewrite the percent as a decimal number by dividing it by 100:

`\frac{5\text{\%}}{100}=0.05`

By analyzing the table, you can write the following formula in order to find each Total Amount Paid (in dollars):

`TotalAmountPaid=SaleAmount+\left(SaleAmount\right)\left(0.05\right)`

Therefore, by substituting the corresponding values into the formula and evaluating, you get:

- For $67.50, you get:

`TotalAmountPaid=67.50+\lparen67.50)\left(0.05\right)=70.88`

- For $98.75, you get:

`TotalAmountPaid=98.75+\left(98.75\right)\left(0.05\right)\approx103.69`

- For $399.79, you get:

`TotalAmountPaid=399.79+\left(399.79\right)\left(0.05\right)=419.78`

- For $1,250.00, you get:

`TotalAmountPaid=1250.00+\left(1250.00\right)\left(0.05\right)=1312.50`

- For $12,500.00, you get:

`TotalAmountPaid=12500.00+\lparen12500.00)\left(0.05\right)=13125.00`

Hence, the answer is:
