A home improvement store normally sells 20 foot extension ladders for $225. This week the ladders are discounted by 20%. What is the sale price of the ladders?
The discount on the ladders is $225 x 0.20 = $<<225*0.20=45>>45.
Therefore, the sale price of the ladder is $225 - $45 = $<<225-45=180>>180. Answer: \boxed{180}.
To find the sale price of the 20-foot extension ladders, we need to calculate the 20% discount on the original price.
Step 1: Find the discount amount.
Discount = 20% × Original Price
Discount = 0.20 × $225
Discount = $45
Step 2: Subtract the discount amount from the original price to get the sale price.
Sale Price = Original Price - Discount
Sale Price = $225 - $45
Sale Price = $180
Therefore, the sale price of the 20-foot extension ladders is $180.
