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,
\(\displaystyle\Rightarrow{x}\times\frac{{20}}{{100}}={4.25}\)
\(\displaystyle\Rightarrow{x}\frac{{{4.25}\times{100}}}{{20}}\)
\(\displaystyle\Rightarrow{x}=\${21.25}\)
