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?

1 answer

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}.
