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.

Mr. Robinson gets $5.99 off which is $24.00
Mr. Chang gets $2.50 off which is $22.50

Work: 
29.99x.20=5.99     29.99-5.99 = 24.00
25.00x.10=2.50     25.00-2.50 = 22.50
