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
[tex](3 m^{-2} n^{4} )( -4m^{6} n^{-7} ) \\ \\
=-12 m^{(-2+6)} n^{(4-7)} \\ \\
=-12 m^{4} n^{-3} \\ \\
=- \frac{12 m^{4} }{ n^{3} } [/tex]
So, option F gives the correct answer
