What was the number of children and the number of adults who took the train ride that day, and which pair of equations can be solved to find the numbers?

Answer 1

Options:
A. 20 children and 10 adults
Equation 1: a + c = 30
Equation 2: 3a + c = 50
B. 10 children and 20 adults
Equation 1: a + c = 30
Equation 2: 3a − c = 50
C. 20 children and 10 adults
Equation 1: a + c = 30
Equation 2: 3a − c = 50
D. 10 children and 20 adults
Equation 1: a + c = 30
Equation 2: 3a + c = 50
