divide each price by its area. The smallest quotient is the best buy in $/m^2.
How you factor in the quality is not specified.
Tina wants to buy flannel sheets. She reads that a weight of at least 190 grams per square meter is considered high quality. She finds 3 options for flannel sheets:
1)1,100g of flannel in 6 square meters, $45.
2)1,260g of flannel in 6.6 square meters, $42.
3)1,300g of flannel in 6.5 square meters, $52.
She would like to buy the sheet that meets her requirements for high quality and has the lowest price per square meter. Which option should she buy? Justify your answer.
THANK YOU!!
