In this problem, Shawna is baking two types of items\u2014<strong>cupcakes and muffins<\/strong>\u2014and must manage how much sugar and flour she uses.<\/p>\n\n\n\n<p>We begin by identifying what each item consumes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>One cupcake uses <strong>35g of sugar<\/strong> and <strong>50g of flour<\/strong>.<\/li>\n\n\n\n<li>One muffin uses <strong>30g of sugar<\/strong> and <strong>65g of flour<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p>Let CC and MM represent the number of cupcakes and muffins, respectively. The total amount of sugar used is the sum of sugar in cupcakes and sugar in muffins: 35C+30M35C + 30M. Shawna needs to use <strong>at least<\/strong> 460 grams, so this expression must be <strong>greater than or equal to<\/strong> 460. This gives the inequality: 35C+30M\u226546035C + 30M \\geq 460<\/p>\n\n\n\n<p>For flour, the total used is 50C+65M50C + 65M, and Shawna wants to stay within a maximum of 970 grams. So, the total must be <strong>less than or equal to<\/strong> 970, resulting in: 50C+65M\u226497050C + 65M \\leq 970<\/p>\n\n\n\n<p>These inequalities allow Shawna to figure out how many cupcakes and muffins she can bake without exceeding ingredient limits. They are especially useful in optimization problems, where someone may want to maximize or minimize a certain quantity (e.g., profit or cost) subject to such constraints.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A cupcake requires 35 grams of sugar and 50 grams of flour, and a muffin requires 30 grams of sugar and 65 grams of flour.
