Use Cross Multiplication to figure out the following:

If Pistachio nuts cost $6/200 g

then...

$6 = $N

200g 1000g

6 x 1000 = 200 x N

6000 = 200N

200 200

30 = N

Therefore, the pistachio nuts cost $30/kg, or $30/1000g.

Which of the following is the best deal?

Peanuts $4/100g
Almonds $22/1 kg
Cashews $15/500mg
