Donna bought one pound of jellybeans and two pounds of chocolate for $2. A week later, she bought four pounds of caramels and one pound of jellybeans, paying $3. The next week, she bought three pounds of licorice, one pound of jellybeans, and one pound of caramels for $1.50.

How much would she have to pay on her next trip if she bought a pound of each of the four kinds of candy?

• cost of 1 pound of each of the four kinds of candy = 2 dollars
