Answer:
$3.6
Step-by-step explanation:
We are told that the pie store is having a 20% off sale on all of its pies. The pie you want regularly costs $18.
To find the amount saved with the discount let us find 20% of 18.
[tex]\text{The amount saved with discount}=\frac{20}{100}\times 18[/tex]
[tex]\text{The amount saved with discount}=0.20\times 18[/tex]
[tex]\text{The amount saved with discount}=3.6[/tex]
Therefore, the amount saved with the discount is $3.6.
