1.

In order to calculate how much is 5% of the original value, let's use the following rule of three:


\begin{gathered} 6.50\to100\text{\%} \\ x\to5\text{\%} \\ \\ (6.5)/(x)=(1)/(0.05) \\ x=0.05\cdot6.5 \\ x=0.325 \end{gathered}

So the amount taken off is $0.32.

2.

Subtracting this amount from the original price, we have:


6.50-0.32=6.18

So the final value is $6.18.

3.

A solution in a sentence would be:

The final value after the discount is 0.95 * 6.5 = $6.18.
