Bunyan Farm sells 3 pound and 5 pound bags of onions. The Tuesday morning delivery consists of 34 bags weighing 122 pounds. How
many bags are there of each size?
2 answers:
<span>24 3-pound bags(72 pounds) and 10 5-pound bags(50 pounds). 72+50 = 122 pounds, 24+10 bags = 34 bags</span>
24- 3 pound bags and 10-5 pound bags
I set up a system of equations
3x + 5y = 122
x + y = 34
Multiply the second equation by -3 so that the x's cancel. This gets you y = 10. Plug 10 back in to either original equation and x = 24.
