Growing Strawberries

The number of strawberry plants that will yield a harvest of at least five pints costs $8.00. The water, fertilizer, and other supplies needed to grow one pint of strawberries cost $0.29. If you can sell strawberries to a store for $1.89 a pint, how many pints would you have to grow before you produce a profit of at least $1 per pint?
