A:
Answer:[tex]2x+4y=12[/tex]Step-by-step explanation:step 1Find the unit rates (Divide the total cost by the number of pounds)Wheat flour[tex]\frac{8}{4}=\$2\ per\ pound[/tex]Rye flour[tex]\frac{20}{5}=\$4\ per\ pound[/tex]step 2Letx ----> the pounds of wheat floury ----> the pounds of rye flourwe know thatThe number of pounds of wheat flour multiplied by its unit rate plus the number of pounds of rye flour multiplied by its unit rate is equal to $12soThe linear equation in standard form that represent this problem is[tex]2x+4y=12[/tex]
