the 5% of VAT is computed on the amount 49.30, so the requested cost is: $\Large 49.30 + \left( {49.30 \cdot \frac{5}{{100}}} \right) = ...?$

hint: $\Large \begin{gathered} 49.30 + \left( {49.30 \cdot \frac{5}{{100}}} \right) = ...? \hfill \\ \hfill \\ = 49.3 + 2.465 = ...? \hfill \\ \end{gathered}$

with the correct of 493.80 following what you have written my answer came out as 24.69

8. Michele_Laino

please wait, I update my computation...

9. anonymous

so do I just add the value of 24.69 to 493.80?

ok

$\Large \begin{gathered} 493.80 + \left( {493.80 \cdot \frac{5}{{100}}} \right) = ...? \hfill \\ \hfill \\ = 493.80 + 24.69 = ...? \hfill \\ \end{gathered}$
