Large coffees sold for 3.00 and medium sold for 2.00. How many large and medium coffees did the stand sell if a total of 210.00 was earned \n" ); document.write( "---------- \n" ); document.write( "Quantity Eq: L + M = 90 cups \n" ); document.write( "Value Eq:: 3L + 2M = 210 dollars \n" ); document.write( "--------------------------------------- \n" ); document.write( "Modify for elimination:: \n" ); document.write( "2L + 2M = 2*90 \n" ); document.write( "3L + 2M = 210 \n" ); document.write( "-------- \n" ); document.write( "Subtract and solve for \"L\":: \n" ); document.write( "L = 30 (# of large cups sold) \n" ); document.write( "---------- \n" ); document.write( "Solve for \"M\":: \n" ); document.write( "30 + M = 90 \n" ); document.write( "M = 60 cups (# of medium cups sold) \n" ); document.write( "-------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "----------- \n" ); document.write( " |
