Answer:
Mr. Chang received the better discount
Step-by-step explanation:
Mrs. Robinson bought a novel at a bookstore on sale for 20% off its regular price of $29.99
The price of the novel at a bookstore = 29.99 -(20% × 29.99)
= 29.99 - (0.20 × 29.99)
= 29.99 - 5.998
= $23.99
Mr. Chang bought the same novel at a different bookstore for 10% off its regular price of $25.
The price of the novel at a different bookstore = 25 - (10% × 25)
= 25 - (0.10 × 25)
= 25 - 2.5
= $22.50
Mr. Chang bought the novel at the price of $22.50 and Mrs. Robinson bought the same novel at the price of $23.99.
Therefore, Mr. Chang received the better discount.
