Question 1192849
<br>
The other tutor showed a typical formal algebraic solution method.<br>
If formal algebra is not required and the speed of getting the answer is important, you can try this informal solution method using logical reasoning and simple mental arithmetic.<br>
(1) If all 236 tickets were child tickets, the total sales would have been 236(1.50) = 354.00
(2) The actual total, 604.00, is 604-354 = 250.00 more
(3) The difference in cost between a child ticket and an adult ticket is 4.00-1.50 = 2.50
(4) The number of adult tickets needed to make the additional 250.00 is 250.00/2.50 = 100<br>
ANSWER: 100 adults and 236-100 = 136 child tickets<br>
CHECK: 100(4)+136(1.5)=400+204=604<br>
