15. Devi saves 2/5 of her pocket money each week, spends ¾ of the remainder
\n" ); document.write( " on ice-cream and 70 cents on sweets.
\n" ); document.write( "She finds that she still has 50 cents left.
\n" ); document.write( " How much money does receive each week?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt received
\n" ); document.write( ":
\n" ); document.write( "If she saves 2/5x, then 3/5x remains
\n" ); document.write( "If she spends 3/4 of the remainder then 1/4 of the remainder remains
\n" ); document.write( ":
\n" ); document.write( "\"1%2F4\" * \"3%2F5\"x - .70 = .50
\n" ); document.write( "\"3%2F20\"x - .70 = .50
\n" ); document.write( "\"3%2F20\"x = .50 + .70
\n" ); document.write( "\"3%2F20\"x = 1.20
\n" ); document.write( "Multiply both sides by 20
\n" ); document.write( "3x = 20 * 1.20
\n" ); document.write( "3x = 24.00
\n" ); document.write( "x = \"24%2F3\"
\n" ); document.write( "x = $8.00 is the amt she receives
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this:
\n" ); document.write( "3/5 * 8 = 4.80
\n" ); document.write( "1/4 * 4.80 = 1.20
\n" ); document.write( "1.20 - .70 = .50; confirms our solutions of x = $8.00\r
