There is a formula to figure out questions like this:

The price difference/ the original price and times the whole equation by 100 (to get the percentage).

> ($50/$150) x 100 = 33% (rounded)

Answer:

The answer is the option C

\(33\%\)

Step-by-step explanation:

we know that

\(\$150\) ------> represent the \(100\%\)

so

by proportion

Find what percent has the price increased

\(\frac{100}{150}\frac{\%}{\$}=\frac{x}{200-150}\frac{\%}{\$} \\ \\x=(200-150)*100/150\\ \\x=50*100/150\\ \\x=33.33\%\)
