If I pay $57.50 for 5kg how much is each pack & how many packs do you get?
If I pay $25.50 for 1.9kg how much is each pack & how many packs do you get?
If I pay $100 for 10kg, how much is each pack & how many packs do you get?

Answer 1

Step 1: Determine the weight of 1 pack.
2.4kg = 12 packs
2.4 kg / 12 pack = .2 kg / pack

Step 2: Multiply the weight by weight/pack to find # of packs. Then, divide the cost by # of packs to find the cost per pack.
2.4 kg * .2 kg/pack = 12 packs
$35/12 = $2.92/pack

That should help you do the rest.
