a girl buys three apples and seven oranges for $4.56. if an orange costs $0.28 more than an apple, how much does each fruit cost?
\n" ); document.write( ":
\n" ); document.write( "Let x = cost for an apple
\n" ); document.write( "Then
\n" ); document.write( "(x+.28) = cost for an orange (given information)
\n" ); document.write( ":
\n" ); document.write( "Write an equation for the statement:
\n" ); document.write( "\"girl buys three apples and seven oranges for $4.56.\"
\n" ); document.write( "3x + 7(x+.28) = 4.56
\n" ); document.write( ":
\n" ); document.write( "3x + 7x + 1.96 = 4.56
\n" ); document.write( ":
\n" ); document.write( "3x + 7x = 4.56 - 196
\n" ); document.write( ":
\n" ); document.write( "10x = 2.60
\n" ); document.write( ":
\n" ); document.write( "x = \"2.6%2F10\"
\n" ); document.write( "x = .26 is the cost for an apple
\n" ); document.write( "then
\n" ); document.write( ".26 + .28 = .54 cost for an orange
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in original equation:
\n" ); document.write( "3(.26) + 7(.54) =
\n" ); document.write( ".78 + 3.78 = 4.56 \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
