Problema Solution
find the total weight of the boxes of peacans in a shipment of 3lb boxes of pecans and 2lb boxes of walnuts.
(1) there were 24 fewer 2lb boxes of walnuts than 3lb boxes of peacans.
(2) the total weight of the shipment was 462lb.
Answer provided by our tutors
3p + 2w = 462
and
p - 24 = w
3p + 2(p - 24) = 462
3p + 29 - 48 = 462
5p = 462 + 48 = 510
p = 102
3x102 + 2w = 462
306 + 2w = 462
2w = 462 - 306 = 156
w = 78
102 boxes of pecans and 78 boxes of walnuts
