Answer: 10 weeks
Explanation:
The doctor currently has 12 ounces. She buys a 3 lb jar of treats. She uses 6 ounces of treats each week.
Step 1: Convert the 3 lb jar into ounces.
3 lb x (16 oz/1 lb) = 48 oz
Step 2: Add the 12 ounces she has left to the 48 ounces in the jar.
12 oz + 48 oz = 60 oz
Step 3: Determine when the doctor will run out of treats based on the total amount she has and how many she uses each week.
60 oz x (1 week/6 oz) = 10 weeks
