Answer:
The bottle that costs R59,99 for 375 g is cheaper
Step-by-step explanation:
The given costs of the bottles of honey are given as follows;
The cost of one of the bottles of honey = R89,99 for 530 g
The cost of the other bottle of honey = R59,99 for 357 g
Let 'x' represents the bottle of honey that costs R89,99 and let 'y' represent the bottle of honey that costs R59,99, we have;
The unit cost (cost per gram) for the bottle of honey, 'x', C/gₓ = R89,99/(530 g) ≈ R 0.16979/g
The unit cost (cost per gram) for the bottle of honey, 'y', = R59,99/(357 g) ≈ R 0.168/g
Given that the unit cost of a bottle 'y' ≈ R 0.168/g is less than the unit cost of a bottle of 'x' ≈ R 016979/g, a bottle 'y' is cheaper than the bottle 'x'
Therefore;
The bottle that costs R59,99 for 375 g is cheaper than the bottle that costs R89,99 for 530 g.
