A grocer wants to make a 10-pound mixture of cashews and peanuts that he can sell for $3.29 per pound. If cashews cost $5.60 per pound and peanuts cost $2.30 per pound, how many pounds of each must he mix? \n" ); document.write( "--------------------- \n" ); document.write( "Using 2 equations: \n" ); document.write( "Quantity: c + p = 10 lbs \n" ); document.write( "Value::: 5.6c + 2.3p = 3.29*10 dollars \n" ); document.write( "---------- \n" ); document.write( "Multiply thru the Quantity Eq. by 560 \n" ); document.write( "Multiply thru the Value Eq. by 100 \n" ); document.write( "------------------- \n" ); document.write( "560c + 560p = 5600 \n" ); document.write( "560c + 230p = 3290 \n" ); document.write( "----- \n" ); document.write( "Subtract and solve for \"p\": \n" ); document.write( "330p = 2310 \n" ); document.write( "p = 7 lbs (amt. of peanuts needed) \n" ); document.write( "------ \n" ); document.write( "Solve for \"c\" using c+p = 10 \n" ); document.write( "c + 7 = 10 \n" ); document.write( "c = 3 lbs (amt. of cashews needed) \n" ); document.write( "===================================== \n" ); document.write( "cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
