Question

Now Karen must choose between these three brands of chocolate sauce: Brand X Chocolate Sauce A 700-mL bottle costs $10.50. Brand Y Chocolate Sauce A 1-liter bottle costs $12.50. Brand Z Chocolate Sauce A 100-mL bottle costs $2.00. Based on the unit price, which of the three chocolate sauce brands should Karen buy? Show your work and justify your response

Answer 1

700 ml bottle of Brand X chocolate sauce costs $10.50
1 liter brand Y costs $12.50
100ml brand Z costs $2.00
brand X costs 700/10.5= $66.67 per ml
brand Y costs 1000ml/12.50=$80 per ml
brand Z costs 100/2=$50 per ml
so the cheapest band to buy is brand Z because 1 ml costs $50
