Abigail buys a dress for $12 & a backpack for $10.50. She is also charged 9% sales tax on the dress only. Write an expression that represents total cost abigail had to pay

Answer 1

1.09(12 + 10.50)

Answer 2

Since the tax is only on the dress, I'd say

10.50 + 12.00*1.09

Answer 3

Oops! Thanks, Steve, for catching that.
