Question

Can you please help me my friend says it’s not $6.17 but I think it is what is the right answer please give an explanation cuz my friend wants why it’s $6.17 lol she think it’s $3.25

Answer 1

1.

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

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

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.
