1kg of cremora powdered milk costs R60 and 750g costs R50 . Determine the more effective/ economic way of buying?

To determine the more effective way of buying, we need to calculate the cost per gram for each option.

For 1kg of cremora powdered milk:
Cost = R60
Amount = 1000g
Cost per gram = R60 / 1000g = R0.06/g

For 750g of cremora powdered milk:
Cost = R50
Amount = 750g
Cost per gram = R50 / 750g = R0.0667/g

Therefore, buying 1kg of cremora powdered milk is more cost-effective as it costs R0.06 per gram compared to R0.0667 per gram for 750g.
