A city has two paint supply stores. Store A sells 44-gallon containers of paint. Each container covers 1,296 square feet for $148. Store B sells paint only by the quart. Each quart sells for $9.25 and covers 81 square feet. At each store, the cost of paint is in a proportional relationship to the amount. Find the constant of proportionality for Store A. At which store is paint a better buy?
+37084 I will assume store A sells 4 gallon containers ...not 44 gallon.
$148/4 gal / 1296sqft/gal /4gal = $ .11419 sqft
Store b
$(9.25x4)/1 gal / (81 x4)sqft/1 gal =$ .11419 sqft
They are the same price per sq ft of coverage
