Answer provided by our tutors

let


s = the price of a senior citizen ticket

c = the price of a child ticket


On the first day the school sold 2 senior citizen tickets and 7 child tickets for a total of $121


2s + 7c = 121


The school took in $215 on the second day by selling 10 senior citizen tickets and 5 child tickets


10s + 5c = 215


by solving the system of equations


2s + 7c = 121

10s + 5c = 215


we find


s = $15


c = $13
