Question 1184059
<br>
Let x be the original number of t-shirts.<br>
72 were sold, leaving (x-72)
4/9 of those (x-72) were then sold
1/3 of the original x remained<br>
The total number sold, plus the number remaining, equals the original total:<br>
{{{72+(4/9)(x-72)+(1/3)x=x}}}
{{{72+(4/9)x-32+(1/3)x=x}}}
{{{40=x-(4/9)x-(1/3)x = (2/9)x}}}
{{{x=180}}}<br>
The original number of t-shirts was 180
72 were sold, leaving 108
4/9 of those 108, or 48, were sold, leaving 60, which is 1/3 of the original number.<br>
ANSWER: The total number sold was 72+48=120<br>
