Answer:
John and Jean are part of a dual-income family.
Step-by-step explanation:
John and Jean must be a modern couple where they both have a job outside the home. Both John and Jean have jobs and they each need an account to receive their salary. Thus we can conclude that John has an account to receive her salary and Jean has another account to receive her salary. Also, since every couple has plans together, such as changing a car, buying a house, or raising money to send their kids to college, John and Jean have a third account, which is a joint account where they both keep money.
