Question

Lin’s father is paying for a meal that originally costs $20. He has a 30%-off coupon for the meal. After the discount, a 7% sales tax is applied. What does Lin’s father pay for the meal

Answer 1

He pays 15.40$ because the coupon code is 6$ and the sales tax is 1.40$
The calcul is 30/100= 0.30
0.30 x 20 = 6$

20 - 6 = 14$

Use the same method for the taxes expect addition them to the price
