Answer:

40,800

Step-by-step explanation:

[tex]\bold{METHOD\ 1:}\\\\\begin{array}{ccc}34,000&-&100\%\\\\x&-&20\%\end{array}\qquad\text{cross multiply}\\\\100x=(34,000)(20)\\\\100x=680,000\qquad\text{divide both sides by 100}\\\\x=\dfrac{680,000}{100}\\\\x=6,800\\\\34,000+6,800=40,800[/tex]

[tex]\bold{METHOD\ 2:}\\\\p\%=\dfrac{p}{100}\\\\\text{The price has increased by 20}\%\\\\100\%+20\%=120\%\\\\120\%=\dfrac{120}{100}=1.2\\\\120\%\ of\ 34,000\to1.2\cdot34,000=40,800[/tex]
