Juice is sold in two different sizes. An 18 gl oz bottle costs $1.10. A 36 gl oz bottle costs 2.75. Which is better to buy?

The 18 ounce bottle costs less per ounce and is the better buy

Step-by-step explanation:

First find the cost per ounce for the 18 ounce bottle

1.10 / 18 =.0611111 per ounce

Then find the cost per ounce for the 38 ounce bottle

2.75 / 36 =.076388888

The 18 ounce bottle costs less per ounce

The best buy is the size 48 1/4 oz

Step-by-step explanation:

To find out the unit rate divide the total cost by the total volume

Part 1) Calculate the unit rate for each size

case A) we have

8 1/2 ounce bottle costs $0.99

Convert mixed number to an improper fraction

Find the unit rate

case B) we have

18 2/2 oz. bottle costs $1.49 Convert mixed number

Find the unit rate

case C) we have

48 1/4 oz. carton costs $2.49

Convert mixed number to an improper fraction

Find the unit rate

case D) we have

64 3/4 oz. carton costs $3.75

Convert mixed number to an improper fraction

Find the unit rate

Part 2) which size is the best buy

we know that

The best buy is the one with the smallest unit rate

so

The best buy is the size 48 1/4 oz
