Question

John can buy a 24 oz bottle of ketchup for $2.19 or a 36 oz bottle for $3.79. Which is the better buy

Answer 1

We need to calculate the unit rates for each bottle of ketchup.

Price/number is ounces

2.19/24=0.09125

3.79/36=0.10527

So, the 24 oz bottle is a better deal because it has the lower unit rate.

Answer 2

24 oz bottle of ketchup for $2.19 is the better buy

Explanation:

24/2.19=10.96

36/3.79=9.50

10.96>9.50
