A total of 438 tickets were sold for the school play.They were either adult tickets .There were 62 fewer student tickets sold th

Paladinen [302]

Total number of adult tickets = 250

Total number of student tickets = 188

Step-by-step explanation:

Let

a be the number of tickets for adults

and

s be the number of tickets for students

Then

Eqn 1: a+s=438

Eqn 2: s=a-62

Putting s=a-62in eqn 1

$a+(a-62)=438\\a+a-62=438\\Adding\ 62\ on\ both\\ sides\\2a-62+62=438+62\\2a=500\\Dividing\ both\ sides\ by\ 2\\\frac{2a}{2}=\frac{500}{2}\\a=250\\Putting\ a=250\ in\ eqn\ 2\\s=250-62\\s=188$

Total number of adult tickets = 250

Total number of student tickets = 188
