a concert was held in a school. students tickets cost 5 dollars and regular cost 8 dollars. The school sold 284 tickets for 1600 dollars. Find the number of student tickets and the number of regular tickets sold.

Answer 1

5S+8R=1600
S+R=284

s=284-R
5(284-R)+8R=1600
5*284-5R+8R=1600
3R=1600-284*5
R=60
S=224
