Question

The price of hamburger increased from .50 cent to .60 cent. What is the percent increase

Answer 1

The hamburguer was .50 cent and increased to 0.60 cent. Let's calculate the percent increase:

The percent increase may be calculated using the formula:

percent increase = [(final value - initial value)/initial value]*100

So:

$\begin{gathered} \frac{0.6-0.5}{0.5}\cdot100= \\ \frac{0.1}{0.5}\cdot100= \\ 0.2\cdot100=20 \end{gathered}$

So, the percent increase was 20%
