To find the price of a $320 tablet after a 45% markup, you can calculate the markup amount and then add it to the original price.
The markup is 45% of $320, which can be expressed in different ways:
1. **Calculating the final price directly:**
- You can take the original price and multiply it by 1 plus the markup percentage. This gives you the entire price after the markup.
- This would be \( 320 \times 1.45 \).
2. **Calculating the markup and adding it to the original price:**
- First calculate the markup: \( 320 \times 0.45 \) (which gives you the actual markup amount).
- Then add the markup to the original price: \( 320 + 320 \times 0.45 \).
The valid expressions that can be used are:
- \( 320 \times 1.45 \)
- \( 320 + 320(1.45) \)
Thus, from your options, the valid selections are:
- **320 . 1.45**
- **320 + 320(1.45)**
The other options do not correctly represent how to find the price after a 45% markup.
