Question

A party size bag of Takis cost $5.95. If it's 30% off, but has a sales tax of 7%, what is the final cost?

Answer 1

The bag of Takis now costs $4.46.

Explanation:

We are given that a bag of Takis costs $5.95. We are also told that a markdown of 30% is applied to the product.

`\displaystyle 100\%-30\% = 70\%\\\\(70)/(100)=0.7\\\\5.95 * 0.7 = 4.165 \approx \$4.17`

Our new price is equal to $4.17, but we are told that a sales tax of 7% is also applied to the Takis. Therefore:

`\displaystyle 100\% + 7\% = 107\%\\\\(107)/(100) = 1.07\\\\4.17 * 1.07 = 4.4619 \approx \$4.46`

Therefore, the item with a markdown and sales tax applied is approximately $4.46.
