tickets to a junior high school play cost $1.10 for each adult and $0.40 for each child. if 360 tickets were sold for a total of $282.60, how many tickets of each kind were sold?

• ans no of adult and children tickets sold are 198 and 162 respectively
  
  let x and y be no of adult and child tickets sold respectively
  x+y 360 y =360-x
  x*1.10 + y*0.40 = 282.60
  x*1.10 + 360*0.40 - 0.40 * x = 282.60
  0.7x + 144 =282.60
  0.7 x = 282.60-144 = 138.6 => x=138.6/0.7
  x = 198 y= 162
