You can put this solution on YOUR website!
2 1/2 yards of 44-inch material costs:
+2.5%2A7+=+17.5+ dollars
2 yards of 60-inch material costs:
+2%2A8.5+=+17+ dollars
-----------------------------
The area of cloth of 44-inch material is:
+2.5%2A36%2A44+=+3960+ in2
The area of cloth of 60-inch material is:
+2%2A36%2A60+=+4320+ in2
( note that I converted yds to inches )
---------------------------
The cost per in2 of 44-inch material is:
+17.5+%2F+3960+=+.004419+
The cost per in2 of 60-inch material is:
+17%2F4320+=+.003935+
The 60-inch material is a better buy ( cheaper per in2 )
Hope I got it
