A matinee ticket costs $6 per adult and $1 per child. On a certain day, the total
number of adults (a) and children (c) who saw a movie was 35, and the total money
collected was $70. Which of the following options represents the number of children
and the number of adults who saw a movie that day, and the pair of equations that
can be solved to find the numbers? (4 points)
PM
28 children and 7 adults
Equation 1: a + c-35
Equation 2: 6a + c = 70
PM
0 28 children and 7 adults
Equation 1: a + C-35
Equation 2: 6a-c-70
PM
O 7 children and 28 adults
Equation 1: a + c = 35
Equation 2: 6a - C = 70
3 PM
O 7 children and 28 adults
Equation 1: a + C-35
Equation 2: 6a + C-70
