Algebra.Com's Answer #657840 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The cost of a can of Coca-Cola on January 1, 1960 , was 10 cents. The function C(t)=0.10e^(0.0576t) gives the cost of a can of Coca-Cola, C(t), t years after that.\r \n" ); document.write( "\n" ); document.write( "a.) How much does a can of Coca Cola cost in 1975 (round to nearest penny)? \n" ); document.write( "# of years 60 to 75 = 15 \n" ); document.write( "C(15) = 0.10*e^(0.0576*15) = 0.10*2.3726 = 0.237 = 24 cents if rounded up \n" ); document.write( "------------------------------------------ \n" ); document.write( "b.) In what year will a can of Coca-Cola cost $1.00 (round to nearest whole year). \n" ); document.write( "Solve for \"t\" \n" ); document.write( "1 = 0.10*e^(0.0576t) \n" ); document.write( "e^(0.0576t) = 10 \n" ); document.write( "Take the natural log of both sides to get: \n" ); document.write( "0.0576t = 2.3026 \n" ); document.write( "t = 40 if rounded up \n" ); document.write( "Ans: 1960 + 40 = year 2000 \n" ); document.write( "-------------------------------- \n" ); document.write( "c.) How much does a can of Coca-Cola cost in 2045 ? \n" ); document.write( "1960 to 2045 = 85 years \n" ); document.write( "C(85) = 0.10*e^(0.0576*85) \n" ); document.write( "I'll leave that calculation to you. \n" ); document.write( "Cheers \n" ); document.write( "Stan H. \n" ); document.write( "----------- \n" ); document.write( " |
