Question 1190672
<br>
The other tutor misread the problem.  The 14 milk bars is the number Mark was left with -- not the number he gave to Mary.<br>
x = original number of milk bars
x-5 = number after he ate 5
(x-5)/3 = one share
(x-5)/3+6 = number he gave to Mary<br>
The number he is left with (14) is the original number, minus the 5 he ate, minus the number he gave to Mary:<br>
{{{14 = x-5-((x-5)/3+6)}}}
{{{14 = (2/3)(x-5)-6}}}
{{{(2/3)(x-5)=20}}}
{{{x-5=30}}}
{{{x=35}}}<br>
ANSWER: He started with 35 milk bars<br>
CHECK:
start with 35; eat 5; 30 left
30 divided into 3 equal shares is 10 for each share
number he gave to Mary was one share (10) plus 6 more = 16
number he has left at the end: 30-16 = 14<br>
