Training goal: Compare the cost of useful output
▶ Play this trainingSituation
1. If all of it were used, what would the large pack cost per kg?
- $10 per kg
- $4 per kg
- $5 per kg
2. But 2 kg of the large pack will be wasted.
- Usable weight costs about $6.67 per kg
- Still $4 because that is the package rate
- Waste costs nothing once paid for
3. You can safely split the large pack with a neighbor: 3 kg for you at $12 and 2 kg for them at $8.
- Buy first and assume agreement later
- Treat the $8 contribution as new profit
- Confirm the split and payment first
4. Storing the split pack requires new containers.
- Buy more to justify the containers
- Add their cost and consider reuse
- Ignore containers because you keep them
What you will learn
- Label prices exclude waste
- Confirm sharing before purchase
- Storage has a cost
Your real-life step
Compare one bulk pack by the weight you will use in time.
Questions and answers
Does bulk always save money?
No. You need sufficient use and suitable storage.
Is a neighbor’s reimbursement profit?
No, if it only covers their share of a joint cost.
Should I consume more for the price?
No. Fit purchases to needs rather than needs to pack size.
