The price of hot dogs is $2.00 more than the price of a bag of potato chips. The cost of a soft drink is $4.25 less than the price of two hot dogs. Find the cost of each item. \n" ); document.write( "
Algebra.Com's Answer #562969 by Stitch(470)![]() ![]() ![]() You can put this solution on YOUR website! Let A = Cost of hot dogs. \n" ); document.write( "Let B = Cost of potato chips \n" ); document.write( "Let C = Cost of a soft drink \n" ); document.write( "------------------------ \n" ); document.write( "Equation 1: \n" ); document.write( "Equation 2: \n" ); document.write( "Equation 3: \n" ); document.write( "------------------------ \n" ); document.write( "Notice that all three equations contain an \"A\" variable. \n" ); document.write( "I wrote the equations so that they were already written in terms of A. \n" ); document.write( "Now plug (A-2) into equation 1 for B. Also use (2A - 4.25) for C \n" ); document.write( "Equation 1: \n" ); document.write( " \n" ); document.write( "Simplify the equation \n" ); document.write( " \n" ); document.write( "Combine like terms \n" ); document.write( " \n" ); document.write( "Add 21 to both sides \n" ); document.write( " \n" ); document.write( "Divides both sides by 15 \n" ); document.write( " \n" ); document.write( "-------------------------- \n" ); document.write( "Now plug 2.5 into equations 2 & 3 for \"A\" and solve. \n" ); document.write( "Equation 2: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "------------------------- \n" ); document.write( "Equation 3: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
