Since she spends 3 minutes per math problem and 4 minutes per science problem, the time spent can be expressed as 3x+4y3x + 4y, where xx is the number of math problems and yy is the number of science problems.<\/p>\n\n\n\n<p>The condition &#8220;Her homework took her more than 60 minutes&#8221; translates to the inequality: 3x+4y&gt;603x + 4y &gt; 60<\/p>\n\n\n\n<p>This means the total minutes she spent must be <strong>greater than 60<\/strong> \u2014 not equal to or less than.<\/p>\n\n\n\n<p>To find which scenario could be true, we plug in the values from each of the four answer choices into the inequality.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>In the first option, 8 math and 9 science give exactly 60 minutes. Since the inequality demands more than 60, this option is not valid.<\/li>\n\n\n\n<li>The second option, with 4 math and 6 science, results in just 36 minutes \u2014 well below the minimum requirement.<\/li>\n\n\n\n<li>The third option has Alexia completing 20 math and 10 science problems.
