A history club sold rolls of wrapping paper as a fundraiser. The wrapping paper was sold in small rolls and large rolls.The club earned $3.00 for every small roll sold.The club earned $4.50 for every large roll sold.The club sold 10 more large rolls than small rolls.The club collected $135.00 more from sales of large rolls than from sales of small rolls.
