9-121.

The attendance at the county fair was lowest on Thursday, the opening day. On Friday, $5500$ more people attended than attended Thursday. Saturday doubled Thursday’s attendance, and Sunday had $3000$ more people than Saturday. The total attendance was $36{,}700$. Write and solve an equation to find how many people attended the fair each day. Homework Help ✎

Create an expression to represent this problem using a variable to represent the unknown quantities. Relate each of the daily attendances to one of the days based on the information from the problem.

Let the attendance for Thursday be represented as $x$, how can you represent the other days' attendances?

Daily Attendances:
Thursday $= x$
Friday $= x + 5500$
Saturday $= 2x$
Sunday $= 2x + 3000$
$x + (x + 5500) + 2x + (2x + 3000) = 36700$

Thursday's attendance $(x) = 4700$ people
How many people attended on the other days?
