Answer:
a + c = 150
7.75a + 10.25b = 1470
Step-by-step explanation:
Let a represent the number of adult tickets that were sold.
Let c represent the number of child tickets that were sold.

a + c = 150 - - - - - - - - - - - - - -1
A child ticket cost $7.75 and an adult ticket cost $10.25. If the cinema sold $1470 worth of tickets, it means that
7.75a + 10.25b = 1470 - - - - - - - - -2

3) A contrapositive is formed by negating the hypothesis and the conclusion and switching their positions. So,
"If a person is a banjo player, then the person is a musician"
First we negate:
"If a person is not a banjo player, then the person is not a musician"
And then we switch:
"If a person is not a musician, then the person is not a banjo player"
The answer is A
4) Both the hypothesis and conclusion of X have been negated in Z, so Z is the inverse of X. Thus the answer is C.
