document.write( "Question 814686: I cannot come up with a formula to solve this. If lean hamburger purchased at $1.89 but loses 10% weight during cooking--and regular hamburger costs $1.09 but loses 30% weight during cooking...what would have to be the purchase price of the lean meat in order to make it of equal value to the regular? Thank you!\r

Algebra.Com's Answer #490432 by TimothyLamb(4379)![]() ![]() You can put this solution on YOUR website! L = value of lean hb \n" ); document.write( "R = value of regular hb \n" ); document.write( "--- \n" ); document.write( "L = 1.89 / (0.9) = 2.10 dollars/unit-weight \n" ); document.write( "R = 1.09 / (0.7) = 1.56 dollars/unit-weight \n" ); document.write( "--- \n" ); document.write( "Answer: \n" ); document.write( "at what price p for lean hb is L = R? \n" ); document.write( "p / (0.9) = 1.56 \n" ); document.write( "p = 1.56 * (0.9) = 1.40 \n" ); document.write( "you get the same value as R if you can purchase lean hb at $1.40 per unit-weight \n" ); document.write( "--- \n" ); document.write( "Solve and graph linear equations: \n" ); document.write( "https://sooeet.com/math/linear-equation-solver.php \n" ); document.write( "--- \n" ); document.write( "Solve quadratic equations, quadratic formula: \n" ); document.write( "https://sooeet.com/math/quadratic-formula-solver.php \n" ); document.write( "--- \n" ); document.write( "Convert fractions, decimals, and percents: \n" ); document.write( "https://sooeet.com/math/fraction-decimal-percent.php \n" ); document.write( "--- \n" ); document.write( "Calculate and graph the linear regression of any data set: \n" ); document.write( "https://sooeet.com/math/linear-regression.php \n" ); document.write( " |
