Let x represent the number of hot dogs sold, and let y represent the number of bottled waters sold. Since hot dogs cost $4 each and bottled water costs $2 each, the total cost can be represented by the expression 4x + 2y. The problem states that the total sales were &#8220;less than $12.&#8221; This translates to the inequality:<\/p>\n\n\n\n<p>4x + 2y &lt; 12<\/p>\n\n\n\n<p>Next, we must consider the &#8220;reasonable&#8221; aspect of the solutions. Since x and y represent physical items being sold, they cannot be negative numbers or fractions. Therefore, both x and y must be non-negative whole numbers (integers \u2265 0).<\/p>\n\n\n\n<p>Now we can test each ordered pair (x, y):<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>(-1, 5):<\/strong>\u00a0This is not a reasonable solution because the number of hot dogs (x) cannot be negative.<\/li>\n\n\n\n<li><strong>(0, 6):<\/strong>\u00a0This is a whole number pair. Let&#8217;s test it in the inequality: 4(0) + 2(6) = 0 + 12 = 12. The result is 12, which is not less than 12. Therefore, this solution is incorrect.<\/li>\n\n\n\n<li><strong>(2, 1):<\/strong>\u00a0This is a whole number pair. Let&#8217;s test it: 4(2) + 2(1) = 8 + 2 = 10. The result is 10, which is less than 12. This is a correct and reasonable solution.<\/li>\n\n\n\n<li><strong>(1, 1.5):<\/strong>\u00a0This is not a reasonable solution because the number of bottled waters (y) must be a whole number; you cannot sell half a bottle of water.<\/li>\n\n\n\n<li><strong>(1, 3):<\/strong>\u00a0This is a whole number pair. Let&#8217;s test it: 4(1) + 2(3) = 4 + 6 = 10. The result is 10, which is less than 12. This is also a correct and reasonable solution.<\/li>\n\n\n\n<li><strong>(2, 2):<\/strong>\u00a0This is a whole number pair. Let&#8217;s test it: 4(2) + 2(2) = 8 + 4 = 12.
