Question 358256
Find the total weight of the boxes of pecans in a shipment of 3 lb boxes of pecans and 2lbs boxes of walnuts.
1)there were 24 fewer 2 lb boxes of walnut than 3 lb boxes of pecans.
---
Quantity Equation: w = p -24

2)the total weight of the shipment was 462 lbs
Weight Equation:
2w + 3p = 462 lbs
---
2(p-24) + 3p = 462
2p-48 + 3p = 462
5p = 510
p = 102 (# of boxes of pecans)
----
Since w = p-24, w = 102-24 = 78 (# of boxes of walnuts)
