The school that Stefan goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 3 senior citizen tickets and 1 child ticket for a total of $38. The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. Which equations represents the system that could be used?

3s + c = 38

3s + 2c = 52

Step-by-step explanation:

Given that :

Let cost of senior citizen ticket = s

Cost of child ticket = c

First day :

Number of Senior citizen ticket (s) = 3

Number of child ticket (c) = 1

Total = $38

Second day:

Number of Senior citizen ticket (s) = 3

Number of child ticket (c) = 2

Total = $52

3s + c = 38 - - - (1)

3s + 2c = 52 - - - (2)

a negative exponent is translated as follows:

so, we have
