Samantha's mother spent $78 at a farmers market. She bought the same number of pounds of apples for $1.50 per lb as tomatoes for $2.50 per lb. She also bought half that weight of a farmers cheese that sold for $4.00 per lb. The number of pounds of peaches she bought for $3.00 per lb was one more pound than the farmers cheese. How many pounds of each product did Samantha's mother buy?
