Answer:
She pays 0. 05$
Step-by-step explanation:
Cost per once is 40, peanut butter is 5. 20 divide those 2 you will get 0. 13
Now divide it by the butter price 2. 70/15
It will be 0. 18
Subtract 0. 18-0. 15
Mia can purchase a 40-ounce jar of peanut butter for $5.20 or a 15-ounce jar for $2.70. How much does Mia save per ounce by buying the 40-ounce jar?
She pays 0.05$
