Question 269106: 15 pounds of anchovies are needed for 7 pizzerias for 2 days. How many pounds are needed for 4 pizzerias for 7 days? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! One way to look at it is that anchovies for 4 pizzarias for 7 days
would be the same as 7 pizzarias for 4 days.
That would be twice as much anchovies as 7 pizzarias for 2 days
and that would be lbs
Another way is:
15 a for 7 p for 2 days =
(15/2) a for 7 p for 1 day =
(15/14) a for 1 p for 1 day =
(15/14)x(7) a for 1 p for 7 days =
(15/14)x(7)x(4) a for 4 p for 7 d
30 pounds are needed for 4 pizzarias for 7 days
