The admission fee of a theater is 2.50 for adults and 1.25 for children. On a certain day, 700 people went to the theater for a concert and 1375 was collected. How many children and how many adults attended the concert
let children be Y and adults be X we are told 700 people went in total hence x+y=700 adults paid $2.50 and children paid $1.25 and in total we collected $1375 hence; 2.50 x + 1.25 y = 1375 generating two equations x + y = 700 2.5 x + 1.25 y = 1375
