Final answer:
To determine which supermarket sells the cheapest bread rolls, compare the price per bread roll. Lethabo's supermarket sells their bread rolls for R2.00 per bread roll, while Buy and Save supermarket sells for R2.50 per bread roll. Therefore, Lethabo's supermarket has the cheapest bread rolls.
Step-by-step explanation:
To determine which supermarket sells the cheapest bread rolls, we need to compare the price per bread roll from both supermarkets. Lethabo's supermarket sells their bread rolls in packets of six for R12.00. Therefore, the price per bread roll is R12.00 divided by 6, which is R2.00 per bread roll. Buy and Save supermarket sells their bread rolls in packets of two for R5.00. Therefore, the price per bread roll is R5.00 divided by 2, which is R2.50 per bread roll.
Comparing the prices, we can see that Lethabo's supermarket sells their bread rolls for a cheaper price of R2.00 per bread roll, while Buy and Save supermarket sells their bread rolls for R2.50 per bread roll. Therefore, Lethabo's supermarket sells the cheapest bread rolls. If you were to advise Mr. Kekana where to buy bread rolls, you would recommend Lethabo's supermarket, as they offer a cheaper price per bread roll.
