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=}(V2-V1)/(V1)*100`

Where:

V1 = Old value

V2 = New Value

In this case.

Old value = 0.2

New Value = 2.19

Therefore:

`\begin{gathered} \text{Percent change=}(2.19-0.2)/(0.2)*100 \\ \text{Percent change=}9.95*100 \\ \text{Percent change=}995 \end{gathered}`

Answer:

995%
