Final answer:
After calculating the cost per kilogram for both options, the 50kg sack of rice offered by the wholesaler at $1.18 per kilogram is the most cost-effective choice for Nazim.
Step-by-step explanation:
To determine which rice Nazim should buy based serving his customers at the most cost-effective price, we need to calculate the cost per kilogram for each option and then compare the prices to figure out the best deal.
For the Basmatic rice sold at the supermarket with the buy 3 get the 4th free offer, we have the following:
- Buy 3 at $1545 = $1545 x 3 = $4635 for 30kg of rice
- Plus 1 free with the offer = 40kg in total
This gives us a cost of $4635 / 40kg = $115.875 per kilogram of Basmatic rice.
For the 50kg sack of rice offered by the wholesaler, we have:
This gives us a cost of $59 / 50kg = $1.18 per kilogram of rice.
Comparing the two, it is clear that the 50kg sack of rice from the wholesaler offers the lowest cost per kilogram and therefore is the most economical option for Nazim.
