<PRE><B>Question 182444</B>
Suppose you invest $1500 in equipment to put pictures on t-shirts. You buy each t-shirt for $3. After you have placed the picture on a shirt, you sell it for $20. How many T-shirts must you sell to break even ?
:
C=3s+1500......C is the cost and s is the number of t shirts
R=20s..........R is the revenue
:
set C=R
:
3s+1500=20s
:
17s=1500
:
{{{highlight(s=88.23)}}}shirts.... you cant sell a partial shirt 
:
so between 88 and 89 shirts sold is break even </PRE>
