Leslie is saving to purchase a Ferrari. She has no money to invest now, but will invest $3,200 each year for 15 years. By the end of the 15 years she will have her business established and will be able to make payments of $1,000 into the account each month. Finally she will let the money sit for ten years without making any payments and it will grow to $1,000,000, at which time Leslie can purchase the Ferrari of her dreams. Leslie's investment will earn 7.00%, monthly. How many payment of $1,000 must Leslie make in order for this plan to work?
