You want to set up a proportion.
(27/18)=(x/24)
OpenStudy (anonymous):
Or you can think of it as canceling units ($27/18 boxes)*24 boxes
the juice boxes cancel and you are left with the dollar amount
OpenStudy (anonymous):
so, it would be
27/18= 1.5
1.5/24= .0625
that is not one if the answers:(
OpenStudy (anonymous):
No, (27/18) = 1.5
1.5*24=
Do you know how to cross multiply?
OpenStudy (anonymous):
not the best but yes

if you were to use the proportion you would have 27*24=18x.
OpenStudy (anonymous):
oh,ok
OpenStudy (anonymous):
or 648=18x, then divide by 18 and you have x, the dollar amount
OpenStudy (anonymous):
i am not getting that sorry
OpenStudy (anonymous):
648/18 = x

X=36
OpenStudy (anonymous):
yes, if each box costs 1.50 and you have 24 boxes its 36 dollars
