<PRE><B>Question 1028809</B>
2 1/2 yards of 44-inch material costs:
{{{ 2.5*7 = 17.5 }}} dollars
2 yards of 60-inch material costs:
{{{ 2*8.5 = 17 }}} dollars
-----------------------------
The area of cloth of 44-inch material is:
{{{ 2.5*36*44 = 3960 }}} in2
The area of cloth of 60-inch material is:
{{{ 2*36*60 = 4320 }}} in2
( note that I converted yds to inches )
---------------------------
The cost per in2 of 44-inch material is:
{{{ 17.5 / 3960 = .004419 }}}
The cost per in2 of 60-inch material is:
{{{ 17/4320 = .003935 }}}
The 60-inch material is a better buy ( cheaper per in2 )
Hope I got it</PRE>
