Question

mr. Robinson write a novel and a book store on sale for 20% off its regular price of $29.99. Mr.Chang brought the same novel at a different bookstore for 10% off its regular price of $25.Which person received the better discount

Answer 1

Answer:

Mr. Chang got the better deal.

Step-by-step explanation:

Robertson: He paid 100% - 20% = 80% of the cost of the book.

80% * 29.99 = 80/100 * 29.99 = 2399.2/100  = 23.992

Chang: He paid 10% off $25.00

10% of $25.00 =  2.50 dollars. I'll let you go through the steps to get this.

With the  discount, Mr. Chang paid 25.00 - 2.50 = 22.50

Conclusion

Mr. Chang got the better deal by $1.49
