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) 7 children and 28 adults Equation 1: a + c = 35 Equation 2: 6a − c = 70 7 children and 28 adults Equation 1: a + c = 35 Equation 2: 6a + c = 70 28 children and 7 adults Equation 1: a + c = 35 Equation 2: 6a + c = 70 28 children and 7 adults Equation 1: a + c = 35 Equation 2: 6a − c = 70

Answer 1

Hello!

So the total number of tickets are 35

The equation would be A6 + c1 = 70

Answer 2

We know: The total number of tickets is 35. Another way of saying this is the number of adults plus the number of children equals 35. i.e.:


`Adults+Children=35`

Using the symbols provided we can write this is as:


`a+c=35`


We also know: The total money collected is $75. We know that $6 was collected for every adult or
`6a` and $1 for every child or
`1c`. i.e.:


`(SixDollars * Adults)+(OneDollar \ times Children)= $70`

Using the symbols provided and adding it all up we can write this is as:


`6a+1c=70`

Equation 1:
`a+c=35`
Equation 2:
`6a+c=70`
