Let weight, in pounds, of fruit purchased be W
\n" );
document.write( "As purchase price was 90c per lb, cost of fruit was: 90W
\n" );
document.write( "If cost per pound was 15c less, then price, per lb would've been: 90 - 15, or 75c
\n" );
document.write( "At reduced price, she would've have been able to buy 4 more lbs, or a total of (W + 4) lbs
\n" );
document.write( "Price she'd then pay, at reduced price = 75(W + 4), or 75W + 300
\n" );
document.write( "Since she'd spend the same amount of money, we now get: Original cost of fruit = reduced cost of fruit, OR
\n" );
document.write( "90W = 75W + 300
\n" );
document.write( "90W - 75W = 300 -------- Subtracting 75W from right-side of equation
\n" );
document.write( "15W = 300
\n" );
document.write( "W, or weight of fruit she purchased = , or 20 lbs
\n" );
document.write( "Money she spent or cost of fruit: 20(90c), or 1,800 cents, or  \n" );
document.write( "

\n" );
