Eight hundred tickets are sold for a play. Thirty-five percent of those tickets were sold in advance. Which equation can be used to find the number of tickets sold in advance?

StartFraction 800 divided by 8 Over 35 divided by 8 EndFraction = StartFraction 100 Over 4.375 EndFraction
StartFraction 100 divided by 8 Over 800 divided by 8 EndFraction = StartFraction 12.5 Over 100 EndFraction
StartFraction 35 times 8 Over 800 times 8 EndFraction = StartFraction 280 Over 6400 EndFraction
StartFraction 35 times 8 Over 100 times 8 EndFraction = StartFraction 280 Over 800 EndFraction

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=0.35×800

This can also be expressed as a fraction:

x=35100×800

To put this into a form that resembles the provided options, we can simplify:

x=35×800100

Now let's check the options provided:

  1. 800÷835÷8=1004.375
  2. 100÷8800÷8=12.5100
  3. 35×8800×8=2806400
  4. 35×8100×8=280800

The option that directly relates to 35100×800 would be the fourth one.

Thus, the appropriate equation to find the number of tickets sold in advance is:

35×8100×8=280800

So, the correct answer is:

StartFraction 35 times 8 Over 100 times 8 EndFraction = StartFraction 280 Over 800 EndFraction
