Answer:

Option A

a + s = 1650 ; 3.5a + 2b = 4580

Step-by-step explanation:

a ------> number of adult tickets

s ------> number of student tickets

Total tickets = $ 1650

a +s = 1650

Cost of 'a' number of adult tickets = 3.50*a = 3.5a

Cost of 's' number of student tickets = 2*s = 2b

Revenue raise = $ 4580

3.5a + 2b = 4580
