Answer:
- 3 pounds at $3.87
- 19 pounds at $0.94
Step-by-step explanation:
Let x represent the number of pounds of high-priced jelly beans sold. Then the total revenue was ...
3.87x + 0.94(22 -x) = 29.47
2.93x + 20.68 = 29.47 . . . . . . eliminate parentheses, collect terms
2.93x = 8.79 . . . . . . . . . . . . . . subtract 20.68
x = 3 . . . . . . . . . divide by 2.93
3 pounds of $3.87 jelly beans were sold; 19 pounds of $0.94 jelly beans were sold.
