Question 939977
Bunyan Farm sells 3 pound and 5 pound bags of onions. The Tuesday morning delivery consists of 25 bags weighing 99 pounds. How many bags are there of each size?
--------
Equations:
Quantity:: t + f = 25 bags
Weight::::3t +5f = 99 lbs
------------------
Modify for elimination::
3t + 3f = 3*25
3t + 5f = 99
-----
Subtract and solve for "f"::
2f = 24
f = 12 (# of 5 lb bags)
Solve for "t"::
t + 12 = 25
t = 13 (# of 3 lb bags)
----------------------------
Cheers,
Stan H.
