The pie store is having a 20% off sale on all of its pies. If the pie you want regularly costs $18, how much would you save with the discount? $

Convert to decimal: Determine the discount rate as a decimal. To find the discount, convert the percentage to a decimal by dividing by 100. 20% ÷ 100 = 0.20Calculate discount amount: Calculate the amount of the discount. Multiply the regular price of the pie by the decimal discount rate. $18 × 0.20 = $3.60Verify calculation: Verify the calculation. Check that the multiplication in Step 2 is correct. 20% of $18 is indeed $3.60 because 10% of $18 is $1.80, and double that amount is $3.60.
