Nuts to You Shoppe sells cashews for $15 per kg and pecans for $10 per kg.
\n" ); document.write( "How many kilograms of each should be mixed in order to get 20 kg of a mixture worth $12 per kg?
\n" ); document.write( "Please can you show long hand?
\n" ); document.write( "-------------
\n" ); document.write( "Two variable solution:
\n" ); document.write( "Quantity Equation: c + p = 20 kg
\n" ); document.write( "Value Equation::: 15c + 10p = 12*20
\n" ); document.write( "--------------------------------------------
\n" ); document.write( "Multiply thru the Quantity Equation by 15 to get:
\n" ); document.write( "15c + 15p = 15*20
\n" ); document.write( "---
\n" ); document.write( "Subtract that from the Value Equation and solve for \"p\":
\n" ); document.write( "-5p = -3*20
\n" ); document.write( "p = 12 kg (amt. of pecans needed in the mixture)
\n" ); document.write( "-------------
\n" ); document.write( "Since c+p= 20, c = 20-12 = 8 kg (amt. of cashews needed in the mix)
\n" ); document.write( "==========================
