Answer 1

`\text{ Total bill=\$20.31}`

Step by step explanation:

As a first step, we are going to calculate the total price of the purchase:

`\begin{gathered} \text{Total}=1.29+7.99+3\cdot0.69+1.09+2.49+2\cdot0.99+1.99+0.44 \\ \text{Total}=19.34 \end{gathered}`

To find the 5% sales tax, we can use the definition of percent:

`\begin{gathered} \text{Total}\cdot(percent)/(100)=\text{equivalent number to the percent} \\ 19.34\cdot(5)/(100)=0.967 \end{gathered}`

Then, the total bill with the 5% sales tax would be:

`\begin{gathered} \text{ Total bill=\$19.34+\$0.967} \\ \text{ Total bill=\$20.31} \end{gathered}`
