Can someone with this math question

Question # 46

Total number of people served = 345
If a adult tickets and c child tickets were sold, we can write:

a + c = 345

Cost of each adult ticket was $5 and cost of each child ticket was $3. Total revenue generated was $ 1395. So we can set up the equation as:

5a + 3c = 1395

From first equation the value of c comes out to be c = 345 - a. Using this value in second equation, we get:

5a + 3(345-c) = 1395

5a + 1035 - 3c = 1395

2a = 360

a = 180

This means 180 adult tickets were sold. So answer to this question is option B

Question # 48



So, option F gives the correct answer
