Ava compares peanut butter jars priced per ounce. The small jar costs $2.50 for 10 oz, and the large jar costs $3.60 for 18 oz. What is the more economical option?
a. Small jar at $0.25/oz
b. Small jar at $0.22/oz
c. Large jar at $0.25/oz
d. Large jar at $0.20/oz

Answer

To determine the more economical option between the small and large peanut butter jars, we calculate the cost per ounce for each jar. **Small Jar:** - Price: $2.50 - Volume: 10 oz - Cost per ounce = Price / Volume = $2.50 / 10 oz = $0.25 per oz

The cost per ounce for the small jar is: $0.25

**Large Jar:** - Price: $3.60 - Volume: 18 oz - Cost per ounce = Price / Volume = $3.60 / 18 oz = $0.20 per oz

The cost per ounce for the large jar is: $0.20

**Comparison:** - Small jar: $0.25/oz - Large jar: $0.20/oz The large jar is the more economical option.

The more economical option is: Large jar at $0.20/oz
