Question

Enter an algebraic expression to model the given context. Give your answer in simplest form. The original price p of an item less a discount of 20%. The algebraic expression is

Answer 1

Explanation:

Let

Original price = p

Less Discount = 20%

Total discount paid for the item = 20% of p

= 20/100 * p

= 0.2 * p

= 0.2p

Actual price after discount = 100% - 20%

= 80%

Total price paid for the item = 80% of p

= 80/100 * p

= 0.8 * p

= 0.8p
