document.write( "Question 1066871: A grocer mixed pecans worth $1.12 per pound with cashews worth $0.60 per pound. If she made 100 pounds of a mixture worth $0.73 per pound, how many pounds of pecans are in the mixture? I have tried many times to solve this problem and I cant get it wrong otherwise I get a 0. If you can give me the equations to use I can solve it easily. I have tried the equation 1.12p+.6c=100*.73 and p+c=100 but I get a repeating decimal that doesnt work. thank you for your time. \n" ); document.write( "
Algebra.Com's Answer #682094 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! x=pecans, y=cashews \n" ); document.write( "x+y=100 \n" ); document.write( "1.12x+0.60y=100*0.73=73 \n" ); document.write( "x+y=100 \n" ); document.write( "x=100-y \n" ); document.write( "1.12(100-y)+0.60 y=73 \n" ); document.write( "112-1.12y+0.60y=73 \n" ); document.write( "-0.52y=-39 \n" ); document.write( "y=75 pounds of cashews @0.60=$45 \n" ); document.write( "x=25 pounds of pecans @1.12=$28 \n" ); document.write( "Total $73. \n" ); document.write( "You set it up fine. I did substitution, but you could do elimination. \n" ); document.write( " |
