Algebra.Com's Answer #849440 by CPhill(1959)![]() ![]() You can put this solution on YOUR website! Here's how to calculate the amount Nicole received from her mother:\r \n" ); document.write( "\n" ); document.write( "1. **Determine the time period:** \n" ); document.write( " * Nicole's birthday: April 22, 2001 \n" ); document.write( " * Maturity date: December 25, 2020\r \n" ); document.write( "\n" ); document.write( " The time period is from April 22, 2001, to December 25, 2020. This is a span of 19 years, 8 months, and 3 days. In terms of exact simple interest, we count the exact number of days.\r \n" ); document.write( "\n" ); document.write( " From April 22, 2001 to December 25, 2020, there are 7164 days.\r \n" ); document.write( "\n" ); document.write( "2. **Use the simple interest formula:** \n" ); document.write( " * Future Value (FV) = Principal (P) + Interest (I) \n" ); document.write( " * Interest (I) = P * r * t \n" ); document.write( " * Where: \n" ); document.write( " * FV = Future Value (P 10,000.00) \n" ); document.write( " * P = Principal (what we want to find) \n" ); document.write( " * r = interest rate (20% or 0.20) \n" ); document.write( " * t = time in years (7164 days / 365 days/year ≈ 19.627 years)\r \n" ); document.write( "\n" ); document.write( "3. **Substitute and solve for P:** \n" ); document.write( " * FV = P + P * r * t \n" ); document.write( " * FV = P(1 + rt) \n" ); document.write( " * P = FV / (1 + rt) \n" ); document.write( " * P = 10,000 / (1 + (0.20 * 19.627)) \n" ); document.write( " * P = 10,000 / (1 + 3.9254) \n" ); document.write( " * P = 10,000 / 4.9254 \n" ); document.write( " * P ≈ 2029.92\r \n" ); document.write( "\n" ); document.write( "Therefore, Nicole received approximately **P 2,029.92** from her mother on her birthday. \n" ); document.write( " \n" ); document.write( " |
