When given a <strong>maturity value<\/strong>, interest earned, and time, we can reverse-engineer the interest formula to find the rate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>maturity value<\/strong> includes both the original <strong>principal<\/strong> and the <strong>interest<\/strong> accrued. So, we first subtract the interest from the maturity value to determine the actual principal amount that was invested or loaned. In this case, the maturity value is $8,801 and the interest earned is $81.20, leaving a principal of $8,719.80.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Next, we apply the <strong>simple interest formula<\/strong>: I=P\u00d7R\u00d7TI = P \\times R \\times T<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is rearranged to solve for the rate: R=IP\u00d7TR = \\frac{I}{P \\times T}<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because the time is provided as a fraction of a year (77 days out of 360, using the <strong>banker\u2019s rule<\/strong>), we multiply accordingly. Substituting the values into the formula gives us: R=81.20\u00d73608,719.80\u00d777\u22480.0435R = \\frac{81.20 \\times 360}{8,719.80 \\times 77} \\approx 0.0435<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thus, the interest rate is approximately <strong>4.35% annually<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This method is commonly used in financial calculations involving treasury bills, short-term loans, and bank notes, especially when using 360-day financial years.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>what is the rate when the maturity value is 8801, the interest is $81.20 and the time is 77\/360 days The correct answer and explanation is: To find the rate (annual interest rate), we can use the simple interest formula: Interest=Principal\u00d7Rate\u00d7Time\\text{Interest} = \\text{Principal} \\times \\text{Rate} \\times \\text{Time} However, we are given: We are solving for [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-16651","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/16651","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=16651"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/16651\/revisions"}],"predecessor-version":[{"id":16652,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/16651\/revisions\/16652"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=16651"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=16651"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=16651"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
