Question

Li wants to buy a jacket that is originally priced at $65.00. Today he store is advertising the jacket for 40% off the original price.

Part A: What is the sale price of the jacket?

Part B: Li has a coupon for an additional 10% off the sale price.

What is the price of the jacket after the coupon?

Answer 1

Part A: 
if the price is $65 and if 40% is off so Li should pay 60% of it.
So 60% of $65 is:
60/100 = ?/65 
? is the sale price:
65*60/100 = $39 
Part B:
if he has 10% coupon for off then he should pay 90% of $39:
90/100 = ?/39 
so ? is the answer:
39*90/100 = $35.1 :)))
I hope this is helpful
have a nice day
