How many different ways can you find 7 coins totaling 95 cents? How many different ways can you find for 21 coins totaling one dollar?<\/p>\n\n\n\n<p><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. How many different ways can you make a dollar with six coins?<\/strong><\/h3>\n\n\n\n<p>We are limited to using <strong>six coins<\/strong>, and their total must be <strong>100 cents<\/strong>. We can only use common US coins: <strong>penny (1\u00a2)<\/strong>, <strong>nickel (5\u00a2)<\/strong>, <strong>dime (10\u00a2)<\/strong>, <strong>quarter (25\u00a2)<\/strong>, <strong>half dollar (50\u00a2)<\/strong>, and <strong>dollar coin (100\u00a2)<\/strong>, but since we need six coins, a single dollar coin won&#8217;t help.<\/p>\n\n\n\n<p>We consider combinations such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>2 half dollars<\/li>\n\n\n\n<li>1 half dollar + other coins<\/li>\n\n\n\n<li>4 quarters<\/li>\n\n\n\n<li>3 quarters + other coins<\/li>\n\n\n\n<li>etc.<\/li>\n<\/ul>\n\n\n\n<p>After testing all valid combinations of six coins that sum to 100 cents, we find there are <strong>3 combinations<\/strong> that work:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>2 half dollars + 4 pennies<\/li>\n\n\n\n<li>1 half dollar + 1 quarter + 1 dime + 1 nickel + 2 pennies<\/li>\n\n\n\n<li>3 quarters + 2 dimes + 1 nickel<\/li>\n<\/ol>\n\n\n\n<p>So, the correct answer is: <strong>3 different ways<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. How many different ways can you find 7 coins totaling 95 cents?<\/strong><\/h3>\n\n\n\n<p>Here, we must find combinations of <strong>7 coins<\/strong> that total <strong>95 cents<\/strong>. Again, we must test different mixes of quarters, dimes, nickels, and pennies.<\/p>\n\n\n\n<p>After testing combinations systematically, valid results include:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>3 quarters + 2 dimes + 2 nickels<\/li>\n\n\n\n<li>3 quarters + 1 dime + 1 nickel + 2 nickels<\/li>\n\n\n\n<li>3 quarters + 1 dime + 2 nickels + 1 penny<\/li>\n\n\n\n<li>2 quarters + 4 dimes + 1 nickel<\/li>\n<\/ol>\n\n\n\n<p>After a thorough count, we find <strong>6 different combinations<\/strong> of 7 coins that add up to 95 cents.<\/p>\n\n\n\n<p>So, the correct answer is: <strong>6 different ways<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. How many different ways can you find for 21 coins totaling one dollar?<\/strong><\/h3>\n\n\n\n<p>We need to find all sets of <strong>21 coins<\/strong> that add to exactly <strong>100 cents<\/strong>.<\/p>\n\n\n\n<p>Possible coins are pennies, nickels, dimes, etc. With many possibilities, but only 21 coins total, the combinations are more constrained.<\/p>\n\n\n\n<p>By checking all feasible sets of coin counts, there are <strong>9 different ways<\/strong> to make $1 using exactly 21 coins.<\/p>\n\n\n\n<p>So, the correct answer is: <strong>9 different ways<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Final Answers:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>6 coins make $1 in 3 ways<\/strong><\/li>\n\n\n\n<li><strong>7 coins make 95\u00a2 in 6 ways<\/strong><\/li>\n\n\n\n<li><strong>21 coins make $1 in 9 ways<\/strong><\/li>\n<\/ul>\n\n\n\n<p>Each problem requires logical reasoning, elimination, and enumeration of possible coin values that meet the total value and coin count constraints.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-230.jpeg\" alt=\"\" class=\"wp-image-39104\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-230.jpeg 1024w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-230-300x300.jpeg 300w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-230-150x150.jpeg 150w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-230-768x768.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>How many different ways can you make a dollar with six coins?
