The very first step is for you to assign meaning to any variables.

In this case, the question asks, "How many tickets were sold in all", so that's a good place to start.

"Let x = the total number of tickets".

We know that they sold 10+14 tickets, and that was 32% of the total number of tickets

24 = x * 32/100

Now you have an equation you can solve. That equals sign is a mighty powerful thing. It lets us do just about anything we want, as long as we do it to both sides. Right now, x is tangled up with being **multiplied** by 32/100. To get rid of that, we **divide **by 32/100 to both sides. This is the same as multiplying by 100/32, to both sides.

24 * 100/32 = x * 32/100 * 100/32

The right-hand-side fractions cancel each other out.

2400/32 = x

simplify the left hand side a little

300/4 = x

then finish simplifying the left hand side.

75 = x = the total number of tickets

This is the answer they are looking for, I think. But the way you phrased it, the correct answer is just 24. You asked for the number of tickets sold, 10+14. We don't know if any more tickets were sold. It could be that the rest of the tickets were never sold, the seats remained empty, and the theatre program was sad.
