In one hour, a bakery sold 5 muffins and 9 bagels for total of $25.50. The next hour, the bakery sold 3 muffins and 12 bagels for a total of $28.50. Let m represent the price of one muffin and b represent the cost of one bagel. Draco wrote the following system of linear equations to solve for the cost of each item. 5 m + 9 b = 28.50. 3 m + 12 b = 25.50. What is Draco’s error? Draco should have set the first equation equal to 25.50 and the second equation equal to 28.50. Draco should have written the first equation as 3 m + 9 b = 25.50. Draco should have written 9b in the second equation and 12b in the first equation. Draco should have written the second equation as 5 m + 12 b = 28.50.
