A(b + c) = a*(b + c) = a*b + a*c
You must multiply individual terms and see what it would equal
Box 1) (LxW) 20x6=120
box 2) (LxW) 15x4=60
box 1 cost) (size of box x price of box) 120x1.25=150
box 2 cost) (size of box x price of box) 60x1.25=75
subtract 150 and 75 to get 75
answer: the company is saving $75 by choosing to make 50 of box 2 instead of 50 of box 1
hope this makes sense comment if you need more explanation
The greatest common factor of 12 and 6 is 6.
5: 90 can also be written as a fraction 5/90 then reduce the fraction
5/90 (5*1=5/5*18=90) so it reduces to 1/18
the ratio simplified is 1:18
C=pi(d)
So d=7ft
Then pi(7ft)=21.98
