A zoo train ride costs $5 per adult and $1 per child. On a certain day, the total number of adults (a) and children (c) who took the ride was 17, and the total money collected was $65. 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? 5 children and 12 adultsEquation 1: a + c = 17Equation 2: 5a − c = 65 12 children and 5 adultsEquation 1: a + c = 17Equation 2: 5a + c = 65 12 children and 5 adultsEquation 1: a + c = 17Equation 2: 5a − c = 65 5 children and 12 adultsEquation 1: a + c = 17Equation 2: 5a + c = 65
