First, make sure you understand the problem. What the problem is really asking is the following:   How many adult tickets were sold? How many children tickets were sold?   Guess and check!   Pretend that 3 children tickets were sold. Then, 17 adult tickets were sold   Total cost = 3 × 5 + 17 × 12 = 15 + 204=

<output>219</output>
219   The total is too high. Pretend that 14 children tickets were sold. Then, 6 adult tickets were sold   Total cost= 14 × 5 + 6 × 12 = 70 + 72= 
<gadget id="calculator">70 + 72</gadget>
<output>142</output>
142   The total is a little too low now. Pretend that 12 children tickets were sold. Then, 8 adult tickets were sold   Total cost= 12 × 5 + 8 × 12 = 60 + 96= 
<gadget id="calculator">60 + 96</gadget>
<output>156</output>
156   As you can see, it is going higher again and it is getting closer to 163. May be 11 tickets for children and 9 tickets for adults will work   Total cost= 11 × 5 + 9 × 12 = 55 + 108= 
<gadget id="calculator">55 + 108</gadget>
<output>163</output>
163   Here we go! 11 children and 9 teachers went to the play   Answer 9
