Algebra.Com's Answer #10590 by josmiceli(19441)![]() ![]() You can put this solution on YOUR website! Let x = last years spending \n" ); document.write( "this years spending was 5 billion more, or x + 5 \n" ); document.write( "this years spending was equal to last years plus 22% of last years \n" ); document.write( "(1.22)x = x + 5 \n" ); document.write( "x + .22x = x + 5 \n" ); document.write( "subtract x from both sides \n" ); document.write( ".22x = 5 \n" ); document.write( "this equation could be your starting point also. It says 5b is 22% of last years spending \n" ); document.write( "x = 5/.22 \n" ); document.write( "x = 22.72 \n" ); document.write( "you want this years speninding, which is x + 5 \n" ); document.write( "x + 5 = 27.72 billion \n" ); document.write( " |
