Answer:

  • 1 pound of expensive chocolate
  • 2 pounds of other chocolate

Explanation:

Let e represent the number of pounds of expensive chocolate in the bag. Then (3-e) is the amount of the other chocolate. The total cost of the bag will be ...

6.00e +4.50(3 -e) = 15.00

1.50e = 1.50 . . . . . . collect terms, subtract 13.50

e = 1 . . . . . . . . . . . . .divide by 1.50

1 pound of expensive chocolate is used; 2 pounds of other chocolate is used.
