My name: Junior Problem: Marvin and his four friends wish to invest in a yacht by sharing equally in the cost. As the date of sale approaches, Marvin realizes that if three more people join the partnership, each partner's share would decrease by $18,000. How much does the yacht cost? Any help is great! Thanks Hi Junior,In this problem there are two important quantities that you don't know. One is the cost of the yacht and the other is the initial amount each of the five partners invested. In order to write some equations I need variable names for these quantities. I will call Y the cost of the yacht and A the amount each of the five partners initially invested, both in dollars. The first sentence Use these two equations for Y to find A, and then Y. Cheers,Penny
