Answer:
Large boxes = 8 Small boxes = 10
Step-by-step explanation:
This took me a while to remember how to do it has been so long!
First, look at just the boxes. Not the weights.
Large boxes + (Small boxes + 2) = Total
Lets use x for boxes.
[tex]x + (x+2) = y[/tex]
now lets factor in weight were total weight equals "y" and pounds of boxes is multiplied by the respective box.
[tex]85x + 50(x+2) = 1180[/tex]
[tex]85x + 50x+ 100 = 1180\\135x+100=1180\\135x+100-100=1180-100\\135x=1080\\\frac{135x}{135} = \frac{1080}{135} \\x=8[/tex]
but remember when we were just looking at the boxes?
Large boxes + (Small boxes + 2) = Total
where large box = x and small box = x+2
this means
large box = 8 and small box = 8+2 = 10
Hope this helps!
