To find the number of tickets sold in advance, we need to calculate 35% of the total ticket sales, which is 800 tickets.
We can use the equation:
\[ x = 0.35 \times 800 \]
This can also be expressed as a fraction:
\[ x = \frac{35}{100} \times 800 \]
To put this into a form that resembles the provided options, we can simplify:
\[ x = \frac{35 \times 800}{100} \]
Now let's check the options provided:
- \( \frac{800 \div 8}{35 \div 8} = \frac{100}{4.375} \)
- \( \frac{100 \div 8}{800 \div 8} = \frac{12.5}{100} \)
- \( \frac{35 \times 8}{800 \times 8} = \frac{280}{6400} \)
- \( \frac{35 \times 8}{100 \times 8} = \frac{280}{800} \)
The option that directly relates to \( \frac{35}{100} \times 800 \) would be the fourth one.
Thus, the appropriate equation to find the number of tickets sold in advance is:
\[ \frac{35 \times 8}{100 \times 8} = \frac{280}{800} \]
So, the correct answer is:
StartFraction 35 times 8 Over 100 times 8 EndFraction = StartFraction 280 Over 800 EndFraction
