Question

When Mc.Donalds opened their shakes cost 0.20. today they cost 2.19 what is the percent change?

Answer 1

Let's use the following formula:

$\text{Percent change=}\frac{V2-V1}{V1}\times100$

Where:

V1 = Old value

V2 = New Value

In this case.

Old value = 0.2

New Value = 2.19

Therefore:

$\begin{gathered} \text{Percent change=}\frac{2.19-0.2}{0.2}\times100 \\ \text{Percent change=}9.95\times100 \\ \text{Percent change=}995 \end{gathered}$

Answer:

995%
