Question

Tickets of a program at college cost ​$4 for general admission or ​$3 with a student ID. If 180 people paid to see a performance and ​$613 was​ collected, how many of each type of ticket were​ sold?

Answer 1

General admission people =73

People with student ID =107

Explanation:

Let general admission people = x

Let people with student ID =y

Now total persons in program =180

So x+y=180

x=180-y

Total cost =613 =4x +3y (as cost specified in question)

Put value of x in above equation.

613=4(180-y) +3y

630=720 -y

y=107

y=107 and x =73
