To determine what percent of the business cards is left, follow these steps:
1. Calculate the number of cards left:
- You start with a total of [tex]\( 600 \)[/tex] business cards.
- You give away [tex]\( 280 \)[/tex] business cards.
[tex]\[
\text{Cards Left} = \text{Total Cards} - \text{Cards Given Away} = 600 - 280 = 320
\][/tex]
2. Calculate the percentage of cards left:
- Take the number of cards left ([tex]\( 320 \)[/tex]) and divide it by the total number of cards ([tex]\( 600 \)[/tex]).
- Multiply by [tex]\( 100 \)[/tex] to convert the fraction to a percentage.
[tex]\[
\text{Percentage Left} = \left( \frac{\text{Cards Left}}{\text{Total Cards}} \right) \times 100 = \left( \frac{320}{600} \right) \times 100
\][/tex]
[tex]\[
\text{Percentage Left} = \left( \frac{320}{600} \right) \times 100 = 53.33\%
\][/tex]
Hence, the percent of the business cards that are left is [tex]\( 53.33\% \)[/tex].
The best answer is:
B. [tex]\( 53.33\% \)[/tex]
