Step 1

Given:

Rate of discount on dozen cupcakes, r = 20%

Amount of discount = 4.25$

Step 2

Let the regular price of a dozen cupcakes = $x

so,

\(\displaystyle\Rightarrow{x}\times\frac{{20}}{{100}}={4.25}\)

\(\displaystyle\Rightarrow{x}\frac{{{4.25}\times{100}}}{{20}}\)

\(\displaystyle\Rightarrow{x}=\${21.25}\)
