HELLPPP ME PLEASE I ONLY KNOW THE LAST QUESTION! I need to have more than three steps! Please help!
B. A discount of 20% is applied to the doll’s original price of $12.99. What is the price of the dolls with the discount applied to $12.99 + 5% tax? Show all of your work!
Hint: Calculate the tax AFTER finding the discount price.
2. The price of an iPad mini is $329. What is the price of the iPad with a 15% discount? Show all of your work!
B. During Christmas, the iPad Mini’s price goes up 10%. There is also a sales tax of 10% added to the increased price. What is the price of the iPad Mini after the increase and sales tax?
Hint: Calculate the tax AFTER finding the increased price.
1. The price of three dolls are $12.99. What is the price of the dolls with a 5% sales tax? Show all of your work!

1B.
12.99 * 0.2 = 2.60 discount
12.99  2.60 = 10.39 new price
10.39 * 0.05 = 0.52 tax
10.39 + 0.52 = 10.91 price for each doll
Study how I found that answer. Then try # 2 yourself.
I'll be glad to check your work. Hint: the new price of the iPad is around $280. 
Oh I asked my teacher she helped me never mind you were right too! Thanks!
