Question

plz help:

The new menu at Tom’s favorite restaurant increased the price of the steak dinner from $12 to $14. What is the percent of change?

Answer 1

percentage change is \[\frac{new - old}{old}*100\%\]

Answer 2

so it went up by $2
it was originally $12

so one could say that $12 was 100%
and $2 increase, is the % in change
so \(\large \begin{array}{cccllll}
quantity&percentage\\
\hline\\
12&100\\
2&x
\end{array}\implies \bf \cfrac{12}{2}=\cfrac{100}{x}\)

Answer 3

thank you
