How ? Give me the perfect answer

ivettef365 · Answer

for example you have equation 4a + 2k = 30 
5 adults and 5 kids

4(5) + 2(5) = 30

20 + 10 = 30
     30 = 30   true so that is ok

ivettef365 · Answer

so find the one that is NOT possible

So, what will be the answer ?

ivettef365 · Answer

ok, since you have 99 I guess I can give you the answer

3 adults and 6 kids

4(3) + 2(6) = 30
12 + 12 = 30
   24 = 30   NOT GOOD
