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?
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?
