21,320 animals / 52 weeks
= 410 animals per week on average
Hope this helped.
Let x=large boxes and y=small boxes.
x+y=110
60x+35y=5100
____________
You need to cancel out one of the variables to solve for one. Let's cancel out y.
-35(x+y=110)
-35x-35y=-3850
60x+35y=5100
____________
Add the two equations.
25x=1250
x=50
_____________
Plug in 50 for x into one of the equations to solve for y.
50+y=110
y=60
_____________
50 large boxes
60 small boxes
A composite has more than 2 ways to divide itself
Add all the x up and then you add all the ones that doesn't have an x then divide those 2 together.
×=46
