store a sells raspberries for $5.50 per pint and blackberries for $3 per pint. store a sells raspberries for $6.50 per pint and blackberries for $8 per pint. a certain purchase of raspberries and blackberries would cost $37 at store a or $66 at store b. how many pints of blackberries are in this purchase?
Final answer:By setting up and solving thesystem of linear equationsbased on the prices and total cost at each store, we can discover that the purchase contains 2 pints of blackberries.Explanation:The subject of the question is mathematics, specifically it's about solving a system of linear equations. We can denote the quantity of raspberries as r andblackberriesas b.Since here Store A sellsraspberriesfor $5.50/pint and blackberries for $3/pint, and the total cost at Store A equaled to $37, we get this equation: 5.5r + 3b = 37.The student has mistakenly listed Store A twice, it's presumed that the second mention is Store B. If Store B sells raspberries for $6.50/pint and blackberries for $8/pint, and totalcostat Store B is $66, this gives us second equation: 6.5r + 8b = 66.To solve these equations to find the quantities of raspberries and blackberries, we can subtract the two equations, eventually giving us b = 2. So thepurchasecontains 2 pints of blackberries.Learn more about system of linear equations here:brainly.com/question/20379472#SPJ11...
