Step-by-step explanation:
Answer:
- 15 @ 41 cents
- 50 @ 56 cents
Step-by-step explanation:
Let x represent the number of 41-cent stamps Yumi bought. Then the number of 56-cent stamps she bought was 4x-10. Her total purchase was ...
0.41x +0.56(4x -10) = 34.15
2.65x -5.60 = 34.15 . . . . . . . eliminate parentheses, collect terms
2.65x = 39.75 . . . . . . . . . . . . add 5.60
x = 15 . . . . . . . . . . . . . . divide by 2.65
4x-10 = 50
Yumi bought 15 41-cent stamps and 50 56-cent stamps.
