Tickets to a museum cost $5.00 for general admission and $2.00 with a student ID. On Friday night

200 tickets were sold for a total of $625. How many general admission tickets were sold?

Number of general admission tickets sold is 75

Step-by-step explanation:

Step 1:

Let the number of general admission tickets be x, then the number of student ID tickets = 200 - x. Total cost of tickets sold = $625

Cost of general admission tickets = 5x

Cost of student ID tickets = 2 (200 - x) = 400 - 2x

Total cost of tickets = 5x + 400 - 2x = 625

⇒ 3x + 400 = 625

⇒ 3x = 225

⇒ x = 75
